Description
Coumarin UV-380 Diethylamino is a coumarin dye reagent identified by CAS number 20571-42-0 and empirical formula C₁₃H₁₅NO₂. It presents an absorption maximum of 380 nm in methanol and a molar mass of 217,27 g/mol, supporting UV-range spectroscopic work, fluorescence studies, and dye chemistry where a diethylamino-coumarin chromophore is required. The material is available from manufacturer Carl ROTH for research and industrial laboratory use. EG number 243-888-7 together with the stated methanol absorption maximum at 380 nm aids consistent specification in analytical protocols and material records. Choose this coumarin derivative when a methanol-referenced absorption maximum near 380 nm is specified for UV dye applications.
This article is part of Fluorescent dyes & labels, in Dyes, stains & indicators.

Questions about Coumarin UV-380 Diethylamino, Absorption maximum (MeOH) = 380 nm, 1 g, glass
What is this article?
Coumarin UV-380 Diethylamino, Absorption maximum (MeOH) = 380 nm, 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.
