4-bromo-N,N-dimethyl-3-(trifluoromethyl)aniline; CAS No.: 51332-24-2; 4-bromo-N,N-dimethyl-3-(trifluoromethyl)aniline. PROPERTIES: This bromo-trifluoromethyl-substituted aniline features molecular formula C?H?BrF?NO with molecular weight 275.13 g/mol. Exists as a liquid. Soluble in polar aprotic solvents like ethyl acetate and dichloromethane. Boiling point approximately 120-125 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 severe skin burns and eye damage. APPLICATIONS: As a brominated aniline, 4-bromo-N,N-dimethyl-3-(trifluoromethyl)aniline 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 bromo and trifluoromethyl substituents.
