  • Used for organic synthesis
  • Used for the synthesis of spices, drugs and so on.
  • GB 2760-1996 provides it as temporarily allowable food spices. It is mainly used to prepare grapes, citrus, rosley, strawberries and watermelon and other types of flavor, but also as the raw materials for the preparation of artificial orange oil.
  • It can be used to prepare flavors of jasmine, orange blossom, gardenia, narcissus, tuberose, white orchid and ylang. It is often used in combination with orange leaf oil in the oriental flavor, heavy flower type and sweet wood type.

PreparationDissolve the anthranilic acid in 5 times the volume of methanol; send into hydrogen chloride; stand 1 h after saturation; then heat to reflux 1h; steam the excess amount of methanol, add sodium hydroxide solution, make it precipitated and obtain the final product through steam distillation or vacuum distillation.
In the presence of sulfuric acid, the o-nitrobenzoic acid and methanol are subject to esterification to generate o-nitrobenzoic acid methyl ester, and then reduced by stannous chloride in ethanol solution, neutralized with alkali and then subject to steam distillation to  derive it.
It can be obtained through the esterification of o-benzoyl formate sodium, sodium hypochlorite and methanol.
In nature, o-aminobenzoic acid methyl ester exists in the tower flower oil, orange blossom oil, ylang, jasmine oil, tuberose oil and so on. Industrial manufacturing is generally achieved by esterification of o-aminobenzoic acid with methanol. The anthranilic acid methanol solution was heated to 65 ° C; add drop wise of sulfuric acid, and generate the sulfate of methyl anthranilate upon reaction at 75 °C. Then neutralize with sodium hydroxide solution to precipitate methyl anthranilate. After extraction with toluene, the toluene extract is washed and the toluene is distilled off. The crude o-aminobenzoate is subjected to vacuum distillation under the conditions of sodium carbonate. The finished fraction is cooled to below 12-15 ° C so that the methyl anthranilate is precipitated out. Another method is by the phthalic anhydride by ammoniation, degradation and esterification to obtain this product.
To the 0 ℃ of ammonia, add phthalic anhydride within 1~2 min. When the temperature rose to 48~50 ℃, add 5 ℃ sodium hydroxide solution; control the temperature at 70 ℃ so that the reaction liquid is maintained alkaline. Under the 60~65 ℃, drain the ammonia for 10 h to obtain the sodium o-formamidobenzoate solution. The mixture was cooled to-12 °C; methanol was added at-10 °C, and a solution of sodium hypochlorite at-10 ° C was added with stirring, and the mixture was allowed to react at 0 °C for 1 hour. And then heat to about 20 ℃. Use potassium iodide starch solution to test until a colorless reaction is reached. Heat to 45 °C to dissolve, transfer into the sedimentation tank for 8h, separate out the mother liquor, take the oil layer for filtration and then stand for layering to obtain the o-aminobenzoic acid methyl ester with the yield of 90% or more.

DescriptionMethyl anthranilate, also known as MA, methyl 2-amino benzoate or carbo methoxy aniline, is an ester of anthranilic acid. Its chemical formula is C8H9NO2.
Chemical PropertiesMethyl Anthranilate occurs in a large number of blossom essential oils (e.g., neroli, ylang-ylang, and jasmine oils), grapes, and citrus oils. It occurs as white crystals (mp 24–25°C), or a yellowish liquid, that show blue fluorescence and have an orange blossom odor. Methyl anthranilate is prepared by esterification of anthranilic acid with methanol or by reaction of isatoic anhydride with methanol.
It is used in a large number of blossom fragrances. However, its use in perfumes for soaps and cosmetics is limited because it causes discoloration. It is used in flavor compositions (e.g., in grape and citrus flavors).
Chemical PropertiesMethyl anthranilate has a characteristic orange-flower odor and a slightly bitter, pungent taste. May be prepared by heating anthranilic acid and methyl alcohol in the presence of sulfuric acid and subsequent distillation.
Chemical PropertiesMethyl anthranilate has a characteristic orange-flower odor and slightly bitter, pungent taste.
Chemical Propertiesyellow to orange liquid with a smell of orange blossom
OccurrenceMethyl anthranilate naturally occurs in the Concord grapes and other Vitis labrusca grapes or hybrids thereof, and in bergamot, black locust, champaca , gardenia, jasmine, lemon, mandarin, neroli, oranges, rue oil, strawberry, tuberose, wisteria, galangal and ylang ylang. It is also a primary component of the essential apple flavor, along with ethyl acetate and ethyl butyrate.It is also secreted by the musk glands of foxes and dogs, and lends a "sickly sweetness" to the smell of rotting flesh.
UsesMethyl anthranilate acts as a bird repellent. It is food-grade and can be used to protect corn, sunflowers, rice, fruit, and golf courses. Dimethyl anthranilate (DMA) has a similar effect. It is also used for the flavor of grape Kool Aid. It is used for flavoring of candy, soft drinks (e.g. grape soda), gums, and drugs.
Methyl anthranilate both as a component of various natural essential oils and as a synthesised aroma-chemical is used extensively in modern perfumery . It is also used to produce Schiff's Bases with aldehydes, many of which are also used in perfumery. In a perfumery context the most common Schiff's Base is known as aurantiol - produced by combining methyl anthranilate and hydroxyl citronellal.
UsesA useful synthetic intermediate.
UsesAs perfume for ointments; manufacture of synthetic perfumes.
DefinitionChEBI: A benzoate ester that is the methyl ester of anthranilic acid.
PreparationBy heating anthranilic acid and methyl alcohol in the presence of sulfuric acid and subsequent distillation.
Aroma threshold valuesDetection: 3 ppb
Taste threshold valuesTaste characteristics at 25 ppm: sweet, fruity, concord grape, with a musty and berry nuance.
General DescriptionClear colorless to tan liquid with an odor of grapes. Has light blue fluorescence.
Air & Water ReactionsMethyl anthranilate is sensitive to air and light. Slightly water soluble .
Reactivity ProfileAn amine and ester. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Fire HazardMethyl anthranilate is combustible.
Safety ProfileModerately toxic by ingestion. Experimental reproductive effects. A skin irritant. See also ESTERS. Combustible liquid. When heated to decomposition it emits toxic fumes of NOx.
ToxicologyMethyl anthranilate is a colorless liquid that has a sweet, fruity, grape-like flavor. It is found in the essential oils of orange, lemon, and jasmine and has been widely used to create imitation Concord grape flavor. Table 10.8 shows the acute toxicity of methyl anthranilate. Methyl anthranilate promotes some allergic reactions on human skin, which has led to it being prohibited for use in cosmetic products.
