Description
La cuivre(II)-octabutoxy-2,3-naphtalocyanine est un colorant de naphtalocyanine de cuivre possédant le numéro CAS 155773-67-4 et la formule brute C₈₀H₈₈CuN₈O₈. Sa masse molaire est de 1353,17 g/mol et elle présente un maximum d'absorption à 849 nm dans le dichlorométhane (DCM), ce qui favorise les travaux dans les études optiques et spectroscopiques du proche infrarouge. Ce colorant de spécialité porte le numéro 812-723-6. Le cœur naphtalocyanine étendu substitué par des groupes octabutoxy et le centre cuivre(II) rendent le matériau pertinent pour la recherche sur les absorbeurs PIR, la caractérisation des colorants et les études photophysiques connexes. Les laboratoires peuvent utiliser le maximum d'absorption défini et les données moléculaires pour planifier des systèmes de solvants, des séries de concentrations et des mesures comparatives.
Cet article appartient aux catégories Colorants et marqueurs fluorescents et Colorants, teintures et indicateurs.

Questions about S 2194 - FEW Chemicals, 849 nm dans du DCM, 1 g, flacon en verre
What is this article?
S 2194 - FEW Chemicals, 849 nm dans du DCM, 1 g, flacon en verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Fluorescent dyes & labels, inside Dyes, stains & indicators, in Produits chimiques de laboratoire et industriels.
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 Dyes, stains & indicators. The sub-category is Fluorescent dyes & labels. The catalogue is Produits chimiques de laboratoire et industriels.
