Description
VIS-546 Trimethine cyanine iodide est un colorant polyméthine du domaine visible, fourni sous forme de cyanine iodide salt. Il porte le numéro CAS 14696-39-0, EG nr. 808-048-1 et la formule empirique C₂₇H₃₃IN₂, avec une masse molaire de 512.48 g/mol. Dans le méthanol, le maximum d'absorption est de 546 nm, positionnant le colorant dans la région visible vert-jaune pour un usage de laboratoire spectroscopique et lié à la coloration. Cette variante est Le matériau provient du fabricant Carl ROTH dans le cadre d'une gamme de colorants couvrant des structures polyméthine pour le travail de recherche et d'analyse. L'architecture triméthine et le maximum MeOH défini de 546 nm aident à distinguer VIS-546 des analogues penta- et heptaméthine à chaîne plus longue. Appliquez les contrôles de laboratoire usuels pour les colorants iodure organiques lors de la pesée, de la dissolution et de l'élimination du matériau. L'identité CAS documentée, la formule empirique et la masse molaire soutiennent une commande précise et la documentation de méthode lorsque VIS-546 cyanine iodide est requis.

Questions about VIS-546 Trimethine-, Cyanine Iodide, 1 g, verre
What is this article?
VIS-546 Trimethine-, Cyanine Iodide, 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.
