CAS 142-82-5
:Heptano
Descrição:
Heptano é um alcano de cadeia reta com a fórmula molecular C7H16, caracterizado por seus sete átomos de carbono e os correspondentes átomos de hidrogênio. É um líquido incolor e inflamável à temperatura ambiente, com um odor distinto que lembra gasolina. Heptano é insolúvel em água, mas solúvel em solventes orgânicos, tornando-o útil em várias aplicações, incluindo como solvente não polar em laboratórios e como padrão de referência em testes de octanagem para combustíveis. Seu ponto de ebulição é relativamente baixo em comparação com alcanos maiores, e apresenta uma alta pressão de vapor, contribuindo para sua volatilidade. Heptano é classificado como um hidrocarboneto e faz parte da série de alcanos, que são compostos saturados com ligações simples entre átomos de carbono. Devido à sua inflamabilidade, deve ser manuseado com cuidado e apresenta riscos à saúde se inalado ou ingerido. Em termos de reatividade, Heptano sofre reações típicas de alcanos, como a combustão, produzindo dióxido de carbono e água. Seu número CAS, 142-82-5, é um identificador único usado para fins regulatórios e de segurança.
