개요
m-toluic acid (MTA) , also known as 3-Methylbenzoic acid or m-Toluate, is a benzoic acid derivative having a floral honey odour. Benzoic acids are organic Compounds containing a benzene ring which bears at least one carboxyl group. Benzoic acid occurs naturally in many plants and its name was also derived from a plant source i.e. Gum benzoin. Although it is used as precursor to plasticizers, preservatives such as sodium benzoate, it also has wide application in many pharmaceutical preparations meant for treatment of fungal skin diseases, topical antiseptics, expectorants, analgesics and decongestants. The benzoic acid derivatives are also very useful due to their bacteriostatic and fragrant properties.MTA is used as intermediate in various chemical reactions, MTA is used as a chemical intermediate in manufacturing of insect repellent and plastic stabilizer in the chemical industry. It is also used in the production of various chemicals like 3-carboxybenzaldehyde, 3-benzoylphenylacetic acid, 3-methylbenzophenone, and N,N-diethyl- 3-methylbenzamide etc.. It is a main component of N,N-diethylm-toluamide, commonly known as DEET, which is first insect repellent that can be applied to skin or clothing and provide protection against mosquitoes and other biting insects.
화학적 성질
White to yellowish crystals. Ionization constant 5.3 × 10?5. Slightly soluble in water; soluble in alcohol and ether. Combustible.용도
m-Toluic acid is used as a reagent in the preparation of hybrid molecules containing oxadiazole and thiadiazole bearing Schiff base moiety as it has antitumor activities.정의
ChEBI: M-toluic acid is a methylbenzoic acid carrying a methyl substituent at position 3. It has a role as a human xenobiotic metabolite. It is a conjugate acid of a m-toluate.일반 설명
White to yellowish crystals or mostly yellow flaky solid (with some white flakes). Has a floral-honey odor.공기와 물의 반응
Fine dust dispensed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. . Insoluble in water.화재위험
Flash point data for m-Toluic acid are not available; however, m-Toluic acid is probably combustible.Purification Methods
Crystallise the acid from water. [Beilstein 9 IV 1712.] Aromatic acid impurities (to <0.05%) can be removed via the (±)--methylbenzylamine salt as described for 2,4-dichlorobenzoic acid [Ley & Yates Organic Process Research & Development 12 120 2008]. The S-benzylisothiuronium salt has m 140o (from aqueous EtOH).메타-톨루일산 준비 용품 및 원자재
