methyl 4-fluoro-2-methyl-5-nitrobenzoate; CAS No.: 1163287-01-1; methyl 4-fluoro-2-methyl-5-nitrobenzoate. PROPERTIES: This fluoro-nitro-substituted methyl ester has molecular formula C?H?FNO? with molecular weight 268.15 g/mol. Appears as a crystalline solid. Soluble in polar aprotic solvents like DMF and DMSO. Melting point approximately 75-80 C. Exhibits IR absorption for ester and nitro groups. Thermogravimetric analysis shows decomposition above 180 C under nitrogen. Store at 2-8 C in tightly sealed containers. May cause skin irritation and eye damage. APPLICATIONS: As a nitro-substituted ester, methyl 4-fluoro-2-methyl-5-nitrobenzoate is used in anti-inflammatory drug synthesis. The nitro group reduces to amine, forming sulfonamide derivatives. Also used in fluorescent probe synthesis, where the ester group enables conjugation via enzymatic hydrolysis. In materials science, it enhances thermal stability in polyurethane foams due to fluorine substituents.
