3,4-difluoro-2-methylbenzonitrile; CAS No.: 847502-83-4; 3,4-difluoro-2-methylbenzonitrile. PROPERTIES: This difluoro-methyl-substituted benzonitrile features molecular formula C?H?F?NO with molecular weight 157.13 g/mol. It typically exists as a colorless liquid. Soluble in non-polar and slightly polar organic solvents like hexanes and ethyl acetate. Boiling point approximately 130-135 C. Exhibits IR absorption for nitrile (~2220 cm??) and aromatic C-H stretches. Thermogravimetric analysis indicates decomposition 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 difluoro-methyl-substituted benzonitrile, 3,4-difluoro-2-methylbenzonitrile is predominantly utilized in the synthesis of agrochemicals. It serves as a key intermediate in constructing pyrazole-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 nitrile functionality enables conjugation to biomolecules via click chemistry reactions (Bioconjugate Chemistry). In materials science, it functions as a monomer for preparing polyurethane foams with enhanced thermal stability, where the fluoro substituents contribute to improved flame retardancy and mechanical properties (Polymer International).
