Description and Uses
In organic synthesis, 3-Methyl-4-nitrobenzoic acid (abbreviated as MNBA) is the fine chemical product that adds value is higher; many critical organic products are obtained for raw material can synthesize further with it, as 4-chloro-quinazoline-6-ethyl formate, 2-n-propyl-4-methyl-6-carboxy benzimidazole, 4-methyl-2-ethyl-1H-benzoglyoxaline-6-methyl-formiate, 3,4-dihydro-4-quinazoline is with-6-formic acid, 4-aminophenyl-1,3-dioctyl phthalate, 4-Amino-3-methylbenzoic acid methyl esters, 4-nitrophenyl-1,3-dioctyl phthalate etc. In medicine, it is an essential intermediate in the synthesis of telmisartan (via esterification, reduction, butyrylation, nitration, reduction and cyclization), which is used to treat essential hypertension. Telmisartan is a drug belonging to the group of antagonists of angiotensin II receptors. The active ingredient telmisartan counteracts the effect of angiotensin II, allowing the arteries to relax, thereby reducing blood pressure. As a precursor, pharmaceutical researchers have also synthesized anti-cancer substances and AIDS drugs with MNBA[1].
3-Methyl-4-nitrobenzoic Acid is used as a reagent in the synthesis of influenza neuraminidase inhibitors with pyrrolidinobenzoic acid scaffold containing lipophilic side chains.
