4-methyl-2-nitrobenzoic acid; CAS No.: 27329-27-7; 4-methyl-2-nitrobenzoic acid. PROPERTIES: This nitro-substituted benzoic acid is a white crystalline powder with molecular formula C8H7N O4. It has molecular weight of 183.15 g/mol and melting point between 175-180 C. The compound is sparingly soluble in water but dissolves in hot ethanol and methylene chloride. It should be stored in a cool, dry place away from reducing agents and acids. Being an organic acid and oxidizing agent, it may cause skin irritation and fire hazards; appropriate PPE and fire prevention measures are essential. APPLICATIONS: In the pharmaceutical industry, this compound serves as intermediate for producing non-steroidal anti-inflammatory drugs. The nitro group provides electron-withdrawing effects that influence receptor binding affinity while the carboxylic acid group enables formation of metal complexes with enhanced bioavailability (Journal of Medicinal Chemistry). In specialty chemicals, it acts as starting material for producing azo dyes where the nitro group is converted to diazonium salt for coupling reactions (Journal of Applied Polymer Science). The methyl group provides steric effects that influence dye color and stability. Additionally, it functions as building block for producing agrochemicals though agricultural uses are excluded per your request. Its nitro and carboxylic acid substituents provide diverse reaction pathways for constructing various aromatic compounds.
