Nicotinic acid Chemical Properties,Uses,Production

Chemical Properties

White crystal or crystalline powder, odorless or has a slight odor, slight sour taste. Melting point is 234-237℃. Easily soluble in hot water, hot ethanol, alkaline water, propylene glycol, and chloroform. Slightly soluble in water and ethanol; 100ml room temperature water can dissolve 1.6g. Insoluble in ether and ester solutions. The PH of 1% aqueous solution is 3.0-4.0. Stable in heat, acidity and alkalinity.



Nicotinic acid exists naturally in grain germs, meats and peanuts. It can also be synthesized artificially through the liquid phase method (potassium permanganate oxidation and nitric acid oxidation) and gas phase method (ozone oxidation, ammonia oxidation and air oxidation). In the gas phase ammonia oxidation process, add 3-methyl pyridine, air and ammonia into the fluidized bed reactor and catalyze the reaction at 290~360℃,V2O5 to produce nicotinonitrile; then hydrolyze in sodium hydroxide aqueous solution at 160℃ to produce sodium nicotinate; finally, add hydrochloric acid to acidify, creating nicotinic acid. In the potassium permanganate oxidation method, add potassium permanganate gradually at 80℃ to a mixture of 3-methyl pyridine and water, and then continue to mix for 30min at 85~90℃. Distill to collect and reuse the unreacted 3-methyl pyridine and filter away the produced manganese dioxide. Adjust the PH of the resulting nicotinic acid solution to 3.8~4.0 using hydrochloric acid, cool to 30℃ crystals, and filter to obtain crude nicotinic acid. Dissolve the crude nicotinic acid in hot water, add activated charcoal to eliminate the color, filter, cool, and obtain the crystalline end product. Yield is approximately 86%. Add sulfuric acid and quinoline into a reaction kettle and mix while maintaining heat at 150~160℃ for 5h. Then with the temperature maintained at 180~220℃, slowly drop in nitric acid and the sulfuric acid mixture over the course of 36~40h. While maintaining the temperature, mix for 2~3h to obtain a nicotinic acid solution and add water to dilute the solution. Use 30%~33% NaOH solution to neutralize the PH to 8~9. Cool and filter away the sodium sulfate and sodium nitrate crystals, add copper sulfate solution to the filtered liquid, and mix and heat to yield copper nicotinate precipitation. Cool, filter and add the copper nicotinate to an adequate amount of water, drop in NaOH solution until PH>9 and the liquid is no longer blue, and filter away the produced cupric oxide. Add a small amount of sodium sulfide solution to remove traces of copper and iron until the solution no longer produces black precipitate, and then filter. Use hydrochloric acid to adjust the PH of the filtered liquid to 3.5~3.9, filter to yield crystals as crude nicotinic acid. Dissolve the crude product in 12 times the amount of distilled water, add activated charcoal to eliminate the color, filter, cool, and obtain the crystalline end product. Yield is 35%~39%. With 2-methyl-5-ethyl pyridine as the raw ingredient, oxidize with nitic acid under high pressure and high temperatures, then decarboxylate to yield nicotinic acid.

Identifying tests

Add 2 portions of 2, 4-Dinitrochlorobenzene to the sample and process into powder. Place 10mg of the powder in a test tube, gently heat until melted, and continue to heat for a couple of seconds. Cool and add 3ml potassium hydroxide ethanol solution (TS-190). The solution should be dark red.
Dissolve 50mg of the sample solution in 20ml water, use 0.1mol/L sodium hydroxide to neutralize until a litmus paper reads neutral, and add 3ml copper sulfate solution (TS-78). Blue precipitate should begin forming slowly.
Dry the sample for 1h at 105℃ and collect its mineral oil dispersions. The peak wavelength of its infrared absorption spectrum should resemble the standard reference sample formulated using the same method.
Prepare an aqueous solution of the sample with a density of 20μg/ml, measure its absorbance at the wavelengths 237nm and 262nm in a 1cm pool, using water as a blank control. A237/A262 should be 0.35~0.39.

Content analysis

Precisely take a sample of 300mg and dissolve in 50ml water. Add a couple drops of phenolphthalein solution (TS-167) and titrate using 0.1mol/L sodium hydroxide. Conduct a control experiment at the same time. Every Ml0.1mol/L sodium hydroxide is equivalent to 12.31mg nicotinic acid (C6H5NO2).


LD50 7.0g/kg (Large mice, oral).

Nicotinic acid. It is a precursor of the coenzymes NAD and NADP. Widely distributed in nature; appreciable amounts are found in liver , fish, yeast and cereal grains. Dietary deficiency is associated with pellagra. The term “niacin” has also been applied


antihyperlipidemic, vitamin (enzyme cofactor)




niacin is also known as vitamin B3. It is a water-soluble conditioning agent that improves rough, dry, or flaky skin, helping smooth the skin and improve its suppleness. niacin enhances the appearance and feel of hair, by increasing body, suppleness, or sheen, or by improving the texture of hair that has been damaged physically or by chemical treatment. When used in the formulation of skin care products, niacinamide and niacin enhance the appearance of dry or damaged skin by reducing flaking and restoring suppleness.


Niacin is a water-soluble b-complex vitamin that is necessary for the growth and health of tissues. It prevents pellagra. It has a solubility of 1 g in 60 ml of water and is readily soluble in boiling water. It is relatively stable in storage and no loss occurs in ordinary cooking. Sources include liver, peas, and fish. It was originally termed nicotinic acid and also functions as a nutrient and dietary supplement.


ChEBI: A pyridinemonocarboxylic acid that is pyridine in which the hydrogen at position 3 is replaced by a carboxy group.

brand name

Niacor (Upsher Smith); Niaspan (KOS); Nicolar (Sanofi Aventis); Wampocap (Medpointe).

Water soluble.

Reactivity Profile

Nicotinic acid is incompatible with strong oxidizers. Nicotinic acid is also incompatible with sodium nitrite.

Fire Hazard

Flash point data for Nicotinic acid are not available; however, Nicotinic acid is probably combustible.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion, intravenous, and subcutaneous routes. Human systemic effects: change in clotting factors, changes in platelet count. Questionable carcinogen with experimental carcinogenic data. When heated to decomposition it emits toxic fumes of NOx.
