Cétones
Les cétones sont des composés organiques caractérisés par la présence d'un groupe carbonyle (C=O) lié à deux atomes de carbone. Ces composés sont très polyvalents et jouent un rôle crucial dans diverses réactions chimiques, notamment l'oxydation, la réduction et la condensation. Les cétones sont des intermédiaires essentiels dans la synthèse de produits pharmaceutiques, de parfums et de polymères. Chez CymitQuimica, nous proposons une large gamme de cétones de haute qualité pour soutenir vos applications de recherche et industrielles.

CAS :<p>Naltrexone is a drug that is used in the treatment of addiction to opioids and alcohol. It has been shown to inhibit the breakdown of endorphins, which leads to reduced pain sensitivity.

This binding prevents the euphoric effects associated with opioid abuse while still allowing pain relief. The use of naltrexone in inflammatory bowel disease was first proposed in 1978 based on its ability to reduce colonic motility in animal models and its subsequent effect on gut function.</p>Formule :C21H23NO3·HClDegré de pureté :Min. 95%Couleur et forme :White PowderMasse moléculaire :373.87 g/mol(3S)-3-(tert-Butoxycarbonyl)amino-1-chloro-4-phenyl-2-butanone
