Description
VIS-519 Trimethine- est un colorant merocyanine polymethine avec le numéro CAS 233748-97-5 et la formule empirique C₂₂H₃₃N₃O₂. Il présente un maximum d'absorption dans le methanol de 519 nm et une masse molaire de 431.58 g/mol, enregistré sous le numéro EG 812-343-0. Le profil de chromophore autour de 519 nm soutient le travail spectroscopique, les protocoles de coloration et les études optiques qui exigent une bande d'absorption visible définie. Le produit du fabricant Carl ROTH est conditionné pour une manipulation pratique en laboratoire et une distribution à petite échelle. Les groupes de recherche peuvent intégrer VIS-519 Trimethine- au développement de méthodes, aux évaluations comparatives de colorants et aux séries analytiques axées sur les structures merocyanine et polymethine apparentées. Il s'intègre aux stocks de produits chimiques, de colorants et de pigments lorsque des colorants polymethine spécialisés sont requis pour un usage scientifique et orienté application.

Questions about VIS-519 Trimethine-, Merocyanine, 1 g, verre
What is this article?
VIS-519 Trimethine-, Merocyanine, 1 g, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Colorants fluorescents & marqueurs, inside Colorants, colorations & indicateurs, in Produits chimiques.
A fluorescent dye absorbs at one wavelength and emits at a longer one. As a label it is attached to a protein, a nucleic acid or a cell. Excitation and emission maxima, and the reactive group if it must conjugate, are the specification. The colour name does not tell you the wavelengths.
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 fluorescents & marqueurs. The catalogue is Produits chimiques.
