Description
Malachite green hydrochloride est un colorant et indicateur de qualité analytique, fourni comme matériau p.a., avec le numéro CAS 123333-61-9 et la formule empirique C₂₃H₂₆N₂O · HCl. La masse molaire est de 382.94 g/mol, ce qui soutient la préparation précise de solutions d'indicateur et de coloration. Classé sous le numéro UN 2811, il est manipulé comme un produit chimique de laboratoire solide pour un usage analytique contrôlé. Ce sel chlorhydrate de malachite green est employé dans l'indication du pH et les applications associées de changement de couleur en chimie analytique. Le produit du fabricant Carl ROTH est positionné parmi les produits chimiques analytiques et les indicateurs de pH pour la pratique de laboratoire. Un grade de pureté défini et des données moléculaires claires aident les laboratoires à maintenir des performances cohérentes dans les titrages, la coloration et les systèmes d'indicateurs qui reposent sur ce colorant triarylméthane classique.
Cet article fait partie de Colorants & solutions de coloration pour microscopie, dans Colorants, colorations & indicateurs.

Questions about Malachite green hydrochloride, p.a., 5 g, verre
What is this article?
Malachite green hydrochloride, p.a., 5 g, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Colorants & solutions de coloration pour microscopie, inside Colorants, colorations & indicateurs, in Produits chimiques.
A microscopy stain binds a structure so it can be seen: haematoxylin on nuclei, eosin on cytoplasm, Gram reagents on a bacterial wall. A ready solution and a dry dye to be dissolved are different articles. The method names the stain. A substitute dye is a different method.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
Which category should I open next?
The category is Colorants, colorations & indicateurs. The sub-category is Colorants & solutions de coloration pour microscopie. The catalogue is Produits chimiques.
Shelves beside this one are Colorants fluorescents & marqueurs and Colorants & pigments.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
