Acetonitrila

Descrição:

Acetonitrila, com a fórmula química CH₃CN e número CAS 75-05-8, é um líquido incolor e volátil que é amplamente utilizado como solvente em vários processos químicos. Tem um odor doce distinto e é altamente polar, o que o torna um excelente solvente para uma variedade de compostos orgânicos, particularmente em reações envolvendo nucleófilos. Acetonitrila tem um ponto de ebulição relativamente baixo e uma alta constante dielétrica, contribuindo para sua eficácia na dissolução de sais e outras substâncias polares. É miscível com água e muitos solventes orgânicos, aumentando sua utilidade em aplicações laboratoriais e industriais. Acetonitrila também é utilizado na produção de produtos farmacêuticos, bem como na extração de certos compostos e em técnicas cromatográficas. Embora geralmente seja considerado de baixa toxicidade, a exposição pode levar à irritação da pele, olhos e sistema respiratório, necessitando de medidas de segurança adequadas ao manuseá-lo. Sua estabilidade química e reatividade fazem dele um composto valioso na síntese orgânica e na química analítica.
