Cations d'ammonium quaternaire
Dans cette section, vous trouverez une large variété de building blocks formés à partir d'amines et facilement solubles dans l'eau. Les cations et sels d'ammonium quaternaire se caractérisent par un atome d'azote lié à quatre groupes organiques, créant un ion chargé positivement. Ces composés sont largement utilisés dans des applications telles que les désinfectants, les surfactants et les catalyseurs de transfert de phase. Leur excellente solubilité dans l'eau et leurs propriétés antimicrobiennes les rendent précieux tant dans les environnements industriels que de recherche. Chez CymitQuimica, nous proposons une sélection variée de cations et sels d'ammonium quaternaire de haute qualité pour répondre à vos besoins.
