Description
Coumarin VIS-425 Diethylamino carbonitrile is a coumarin dye reagent with CAS number 51473-74-6 and empirical formula C₁₄H₁₄N₂O₂. It exhibits an absorption maximum of 425 nm in methanol and a molar mass of 242,28 g/mol, making it suitable for visible-range spectroscopic, fluorescence, and dye-chemistry laboratory work that calls for a defined diethylamino-coumarin carbonitrile structure. This reagent is available from manufacturer Carl ROTH for research and industrial laboratory environments. With EG number 808-021-4 and a clear methanol absorption reference at 425 nm, laboratories can specify and document the dye consistently across SOPs and material lists. is practical for evaluation, comparative studies, and controlled consumption in routine or development workflows. Use this coumarin carbonitrile when a VIS absorption maximum near 425 nm in methanol is required.
This article is part of Fluorescent dyes & labels, in Dyes, stains & indicators.

Questions about Coumarin VIS-425 Diethylamino, Carbonitrile, 1 g, glass
What is this article?
Coumarin VIS-425 Diethylamino, Carbonitrile, 1 g, glass 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.
