Beschreibung
NIR-820 Heptamethine cyanine NEt3H+ is een polymethinekleurstof met de empirische formule C₅₂H₆₆ClN₃O₆S₂ en CAS-nummer 289893-03-4. Deze nabij-infrarode cyanine vertoont een absorptiemaximum van 820 nm in methanol en een molaire massa van 928,69 g/mol. De heptamethinestructuur met triethylammonium-tegenion biedt een gekarakteriseerd raamwerk voor onderzoek naar optische eigenschappen diep in het nabij-infrarode gebied. Het product, verkrijgbaar bij fabrikant Carl ROTH onder EG-nummer 812-366-6, behoort tot de klasse van polymethinekleurstoffen en wordt toegepast waar sterke absorptie rond 820 nm nodig is voor methodeontwikkeling, vergelijkende screening of formuleringstests. Het faciliteert nauwkeurige hantering in analytische en synthetische laboratoria die gecontroleerde hoeveelheden gespecialiseerde kleurstof vereisen voor toepassingen op het gebied van beeldvorming en optische materialen.

Questions about S 2161 - FEW Chemicals, 820 nm in MeOH, 1 g, glas
What is this article?
S 2161 - FEW Chemicals, 820 nm in MeOH, 1 g, glas 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 Labor- und Industriechemikalien.
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 Labor- und Industriechemikalien.
Shelves beside this one are Microscopy stains & staining solutions and Dyes & 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.
