N-(3-fluoro-2-methylphenyl)acetamide; CAS No.: 322-33-8; N-(3-fluoro-2-methylphenyl)acetamide. PROPERTIES: This fluoro-methyl-substituted acetamide features molecular formula C?H?FNO with molecular weight 166.17 g/mol. It generally appears as a white crystalline powder. Soluble in polar aprotic solvents like DMF and DMSO. Melting point approximately 100-105 C. Exhibits IR absorption for amide (~1650 cm??) and C-F groups (~1300-1100 cm??). Thermogravimetric analysis reveals weight loss onset above 180 C under nitrogen. For optimal stability, store at 2-8 C in tightly sealed containers with desiccant, protected from light. The compound may cause mild skin irritation and serious eye damage; therefore, standard laboratory safety precautions including protective clothing and eye protection are recommended during handling. APPLICATIONS: As a fluoro-methyl-substituted acetamide, N-(3-fluoro-2-methylphenyl)acetamide is predominantly utilized in the synthesis of agrochemicals. It serves as a key intermediate in constructing acetanilide-based herbicides, where the fluoro and methyl groups provide valuable binding affinity for plant enzymes as demonstrated in pesticide chemistry research (Pest Management Science). Additionally, the compound participates in the development of fluorescent probes for bioimaging applications, where its amide functionality enables conjugation to biomolecules via reductive amination (Bioconjugate Chemistry). In materials science, it functions as a monomer for preparing polyurethane foams with enhanced thermal stability, where the fluoro substituent contributes to improved flame retardancy and mechanical properties (Polymer International).
