• 説明

  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].

• 反応プロフィール

  3-Methyl-4-nitrobenzoic acid is a nitrated carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry.

• 火災危険
