{"product_id":"2-butanone-8403","title":"2-Butanone, min. 99.5 %, pour la synthèse, 1 l, verre","description":"\u003cp\u003e2-Butanone est un solvant de qualité synthèse fourni à une pureté minimale de 99.5 % pour la préparation organique et le travail de procédé. Il est enregistré sous le numéro CAS 78-93-3 et le numéro EG 201-159-0, avec la formule empirique C₄H₈O et une masse molaire de 72.11 g\/mol. Les données physiques comprennent une densité de 0.81 g\/cm³, un point d'éclair de −8 °C et un intervalle d'ébullition de 79 à 80 °C ; le numéro UN est 1193. Ces propriétés rendent la cétone adaptée comme milieu réactionnel, auxiliaire d'extraction ou solvant de nettoyage lorsqu'un composé carbonylé à bas point d'ébullition défini est spécifié. Proposé du fabricant Carl ROTH, le matériau convient aux stocks chimiques standard qui exigent des données claires d'identité, de pureté et de classification des dangers. Observez les contrôles relatifs aux liquides inflammables, un transfert mis à la terre le cas échéant, et un examen complet des données de sécurité avant le stockage ou l'utilisation.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eCet article fait partie de \u003ca
