Description

Crystal violet (C.I. 42555) est un colorant indicateur de qualité p.a. avec le numéro CAS 548-62-9 et la formule empirique C₂₅H₃₀ClN₃. La masse molaire est de 407.99 g/mol, la densité de 1.19 g/cm³, le point d'éclair de 405.1 °C et le point d'ébullition de 631.9 °C, ce qui donne un profil physicochimique clair pour la mise au point de la méthode. La référence Colour Index C.I. 42555 favorise une spécification cohérente dans les protocoles et les enregistrements. Crystal violet du fabricant Carl ROTH est fourni en qualité p.a. pour un usage contrôlé en laboratoire. Le numéro EG 208-953-6 et le numéro UN 3077 facilitent le traitement réglementaire et logistique. L'unité en verre est pratique pour la pesée et la préparation de solutions dans les applications de titrage et d'indicateur. Ce colorant est destiné aux laboratoires d'analyse qui requièrent un réactif crystal violet bien caractérisé pour les procédures indicatrices liées au pH et apparentées.

Cet article fait partie de Solvants de qualité analytique (p.a.), dans Solvants.

Questions about Crystal violet (C.I. 42555), p.a., 25 g, verre

What is this article?

Crystal violet (C.I. 42555), p.a., 25 g, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants de qualité analytique (p.a.), inside Solvants, in Produits chimiques.

An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.

A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
