Pharmaceutical Materials

3-Methyl-4-nitrobenzoic acid, a yellow crystalline compound with the CAS number 3113-71-1, is a valuable intermediate in pharmaceutical and fine chemical industries. Its molecular formula is C₈H₇NO₄, with a molecular weight of 181.15 g/mol. This compound is widely recognized for its role in synthesizing antihypertensive drugs like telmisartan and antiviral agents. It exhibits a melting point of 216–218°C and a boiling point of approximately 356°C. Due to its nitro and carboxylic acid functional groups, it participates in reduction, esterification, and amide formation reactions. Safety precautions include avoiding inhalation and skin contact, as it can cause irritation. Proper storage in cool, dry conditions is essential to maintain stability.

Usage： 3-methyl-4-nitrobenzoic acid is mainly used in organic synthesis intermediates, but also used in medicine, is an important intermediate in the synthesis of antihypertensive drugs telmisartan, and AIDS drugs.

Packaging and Shipping： 25KG/drum or as per buyer requirement.

Storage: Storage in the ventilated low-temperature dry warehouse; Keep the container closed and separately from the open flame and heat source.
