Description
Coumarin VIS-443 TM-BQZ carbonitrile is a coumarin dye with CAS number 115662-11-8 and empirical formula C₂₀H₂₂N₂O₂. Its molar mass is 322,41 g/mol, and the absorption maximum in methanol (MeOH) is 443 nm, making it suitable for visible-range spectroscopic and photochemical applications. This carbonitrile-functionalised coumarin is 812-359-8. The combination of a compact molecular framework, documented molar mass, and a clear absorption maximum supports UV/Vis method setup, dye comparison studies, and educational or research use of coumarin chromophores. Laboratories can apply the MeOH absorption data when selecting solvents, preparing stock solutions, or aligning detector wavelengths.
This article is part of Fluorescent dyes & labels, in Dyes, stains & indicators.

Questions about Coumarin VIS-443 TM-BQZ Carbonitrile, Absorption maximum (MeOH) = 443 nm, 1 g
What is this article?
Coumarin VIS-443 TM-BQZ Carbonitrile, Absorption maximum (MeOH) = 443 nm, 1 g 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 Lab chemicals.
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?

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.
