Resorcinol is an important raw material for organic synthesis. It is mainly used as the raw material of rubber adhesives, raw analysis reagents, drugs and preservatives, dyes, synthetic resin. For example, eosin is an important triphenylmethane dye with red dying which is mainly used for yarn dyeing. It is made from the following process: first generate its intermediate fluorescent yellow thorough the co-heating between resorcinol and phthalic anhydride in the presence of zinc chloride or concentrated sulfuric acid, then apply tetra-bromination to generate it. Eosin is commonly used to produce red ink, also be used as biological material such as the staining agent for microscopic examination. If the intermediate fluorescent yellow is subject to bromination in acetic acid solution, only di-bromination can occur; further co-heating with mercuric acetate can obtain mercurochrome (also known as red mercury bromine) which is an important antiseptic disinfectant. It is easily soluble in water with its 2% aqueous solution being the daily-used “red syrup” for disinfection. The alcohol and acetone solution of mercurochrome may also be used for skin disinfection. Put resorcinol and hexanoic acid for acylation reaction and further reduction can generate 4-n-hexyl hydroquinone which is also a kind of disinfectant. In medicine, it is also used as a topical anti-itch agent and a digestive agent of the intestinal tract.




1. It can be used as the raw materials for the production of synthetic resins, adhesives, dyes and ultraviolet absorbing agent. It can also be used as the dipped cord of tire. Medically it can be used as the disinfection antiseptic agent.
2. Resorcinol is also known as 1, 3-hydroquinone. In the field of pesticides, it can be used as the intermediate 3-chloro-4-methyl coumarin and herbicide oxyfluorfen in the synthesis of pesticides coumaphos. It can also be used for the production of dyes, specialty coatings, pharmaceuticals, photographic material, synthetic resins, adhesives, and cosmetics.
3. Resorcinol is mainly used for the field of rubber adhesives, synthetic resins, dyes, preservative, pharmaceutical and analytical reagents. Resorcinol is similar with phenol and cresol. It can generate condensation polymer through the reaction with formaldehyde. It can be used for making glue silk and the adhesive agent of tire cord for nylon-purpose, making wood glue, and being as the adhesive for vinyl material and metal. Resorcinol is the intermediate of many kinds of azo dyes and fur dyes as well as the raw material of pharmaceutical intermediates, p-nitrogen salicylic acid. Resorcinol has bactericidal effects and can be used as preservatives for being supplied to cosmetics and dermatological drugs pastes and ointments. The resorcinol derivatives, β-methylumbelliferone can be used as the intermediate for optical bleach; tri-nitro resorcinol is detonator. There is also a considerable amount of resorcinol being used in the production of benzophenone-class ultraviolet absorbers. This product can irritate the skin and mucous membranes, can cause poisoning disease through the rapid absorption by the skin. Minimum lethal dose of rat being subject to subcutaneous injection is 450mg/kg.
4. It can be applied to the fields of photographic film, medicines, dyes and chemical fiber industry.
5. It can also be used as reagents for analysis.
6. It can be used for characterization and determination of zinc, lead, tartaric acid, nitrate and nitrite through colorimetric method; it can also applied to the colorimetric reaction for measuring sugar and Furfuryl alcohol; as the reagent for detecting ketone sugars and lignin; it can also applied to the salt reagent of diazonium compound as well as to organic synthesis.


1. Benzene sulfonic acid is sulfonated with oleum; further go through neutralization, alkaline melting, acidification, n-butanol extraction, evaporation of the solvent, and distillation to obtain the finished products. 2. It can be produced through the hydrogenation of m-dinitrobenzene into m-phenylenediamine which is further subject to hydrolysis to get the finished product. 3. It can be produced from the hydrolysis of m-aminophenol. Resorcinol can also derived from benzene and propylene using peroxide di-isopropylbenzene method with the process being similar as isopropylbenzene production.
Put benzene, 65% fuming sulfuric acid and sodium sulfate separately into the reactor; control the reaction temperature at 75 ℃ to obtain the sulphonate. Then add anhydrous sodium sulfate to this sulphonate, stir and heat to 175 ℃ for dissolving it; Add sulfur trioxide at this temperature and continue the reaction for an additional 1.5h to generate di-sulphonate (with the content of benzene disulfonic acid being 75%). Use dilute alkali to neutralize the di-sulphonate and remove the excess amount of sulfate salt; the resulting sodium benzene di-sulfonate is gradually added into the molten sodium hydroxide 290 °C; raise the temperature to 325 °C within 15min and further dissolve the alkali melting substance in water; acidify it with sulfuric acid and extract with ether; evaporate the solvent to obtain the finished resorcinol products.

Chemical Properties

Resorcinol is a white crystalline solid with a characteristic odor and a sweetish taste. Turns pink on expo- sure to air or light, or contact with iron.


Reported found in roasted barley, cane molasses, beer, red wine, white wine, special wine and coffee.


Resorcinol is used in the manufacture of resorcinol–formaldehyde resins, resin adhesives, dyes, drugs, andexplosives; in tanning; in cosmetics; and in dyeing and printing textiles.


In very mild solutions, resorcinol is used as an anti-septic and soothing preparation for itchy skin. In slightly higher concentrations, resorcinol removes the top layer of the stratum corneum and is used particularly in cases of acne. In still higher concentrations, it can act as an aggressive surface skin exfoliant. Resorcinol can also be used as a preservative. While it is a beneficial skin care ingredient when used in low concentrations, it causes irritation in higher concentrations with a strong burning sensation and a reddening of the skin. used in high concentrations as a peel, resorcinol may cause a variety of problems, including swelling. It is is obtained from various resins.


A benzene derivative used as keratolytic and antiseborrheic. Also used in veterinary medicine as a topical antipruritic and antiseptic (has been used as intestinal antiseptic).




An aromatic alcohol used as a chemical intermediate


ChEBI: A benzenediol that is benzene dihydroxylated at positions 1 and 3.


Resorcinol (resorcin), a phenol derivative, is less keratolytic than salicylic acid. This drug is an irritant and sensitizer and reported to be both bactericidal and fungicidal. Solutions containing 1% to 2% have been used in preparations for seborrhea, acne, and psoriasis.

Incompatible with acetadde, alkalies, ferric salts, spirit nitrous ether, urethan. When heated to decomposition it emits acrid smoke and irritating fumes

Potential Exposure

Resorcinol is weakly antiseptic; resorcinol compounds are used in the production of resorcinol-formaldehyde adhesives; or as an intermediate; in pharmaceuticals and hair dyes for human use. Major industrial uses are as adhesives in rubber products and tires, wood adhesive resins, and as ultraviolet absorbers in polyolefin plastics. Resorcinol is also a by-product of coal conversion and is a component of cigarette smoke. Thus, substantial opportunity exists for human exposure.


Acute Toxicity. The primary signs of intoxication resemble those induced by phenol, and include initial stimulation of the CNS, followed by depression, renal glomerular and tubular degeneration, central hepatic necrosis, myocardial depression, pruritus, and reddening of the skin. Resorcinol has been reported to be less toxic than phenol or pyrocatechol by oral and dermal routes.
Resorcinol is a simple aromatic chemical (1,3-benzenediol) that has found widespread use, particularly as a coupler in hair dyes. Clinical experience clearly shows that resorcinol is a skin sensitizer, although several predictive tests have been negative. In a local lymph node assay performed in accordance with OECD Guideline 429, resorcinol was identified as a skin sensitizer.
Few reports of the toxicity of resorcinol have been published. Oral ingestion in humans may cause methemoglobinemia, cyanosis, and convulsions, whereas dermal exposure has been reported to cause dermatitis, hyperemia, and pruritus. Industrial inhalation exposures are rather rare, but could occur in any industry if the compound is heated beyond 300°F.
Pathology reported for humans includes anemia, marked siderosis of the spleen and marked tubular injury in the kidney, fatty changes of the liver, degenerative changes in the kidney, fatty changes of the heart muscle, moderate enlargement and pigmentation of the spleen, and edema and emphysema of the lungs.
