(2-chloro-3-fluorophenyl)methanamine; CAS No.: 72235-54-2; (2-chloro-3-fluorophenyl)methanamine. PROPERTIES: This chloro-fluoro-substituted methanamine features molecular formula C?H?ClFNO with molecular weight 175.60 g/mol. Appears as a liquid. Soluble in polar aprotic solvents like ethyl acetate and dichloromethane. Boiling point approximately 130-135 C. Exhibits IR absorption for amine groups. Thermogravimetric analysis indicates decomposition above 180 C under nitrogen. Store at 2-8 C in sealed containers. May cause skin irritation and eye damage. APPLICATIONS: As a chlorinated amine, (2-chloro-3-fluorophenyl)methanamine is used in pesticide synthesis. The amine group undergoes cyclization to form pyrazoline herbicides. Also used in fluorescent probe synthesis, enabling conjugation via reductive amination. In materials science, it enhances thermal stability in polyurethane foams due to chloro and fluoro substituents.
