CAS 75-05-8
:Acétonitrile
Description :
Acétonitrile, avec la formule chimique CH₃CN et le numéro CAS 75-05-8, est un liquide incolore et volatil qui est largement utilisé comme solvant dans divers processus chimiques. Il a une odeur douce distinctive et est hautement polaire, ce qui en fait un excellent solvant pour une gamme de composés organiques, en particulier dans les réactions impliquant des nucléophiles. Acétonitrile a un point d'ébullition relativement bas et une constante diélectrique élevée, ce qui contribue à son efficacité dans la dissolution des sels et d'autres substances polaires. Il est miscible avec l'eau et de nombreux solvants organiques, augmentant son utilité dans les applications de laboratoire et industrielles. Acétonitrile est également utilisé dans la production de produits pharmaceutiques, ainsi que dans l'extraction de certains composés et dans les techniques chromatographiques. Bien qu'il soit généralement considéré comme ayant une faible toxicité, l'exposition peut entraîner une irritation de la peau, des yeux et du système respiratoire, nécessitant des mesures de sécurité appropriées lors de sa manipulation. Sa stabilité chimique et sa réactivité en font un composé précieux dans la synthèse organique et la chimie analytique.
