2-(aminomethyl)benzonitrile; CAS No.: 344957-25-1; 2-(aminomethyl)benzonitrile. PROPERTIES: This aromatic compound is a colorless liquid with molecular formula C8H7N. Its molecular weight is 117.15 g/mol and it boils at 204-206 C at 760 mmHg. It has density approximately 1.02 g/cm? at 20 C and is miscible with most organic solvents. Recommended storage is in tightly sealed containers at room temperature away from oxidizing agents. Being a nitrile and amine-containing compound, it may form toxic fumes when heated; proper engineering controls should be in place during handling. APPLICATIONS: In the field of materials science, this compound serves as monomer for producing polyimides with enhanced thermal stability. The benzonitrile group participates in imidization reactions when heated with appropriate diamines (Polymer Journal). In pharmaceutical applications, it acts as intermediate for synthesizing benzodiazepine derivatives used as anxiolytic agents. The aminomethyl group enables formation of diazepine ring system through cyclization reactions (Journal of Heterocyclic Chemistry). Additionally, it functions as starting material for producing liquid crystalline compounds where the nitrile group contributes to dipole alignment and the aminomethyl provides reactive site for introducing mesogenic units (Liquid Crystals). These applications exploit its combination of aromatic character, nitrile functionality, and amine reactivity for constructing advanced materials and pharmaceuticals.
