Description and Uses
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.
Organic synthesis, to form N,N-diethyl-mtoluamide, a broad-spectrum insect repellent.
