Description
Coumarin VIS-436 TM-BQZ Et-Ester is a coumarin dye reagent with CAS number 113869-06-0 and empirical formula C₂₂H₂₇NO₄. It exhibits an absorption maximum of 436 nm in methanol and has a molar mass of 369,46 g/mol, supporting spectroscopic and fluorescence-related laboratory work where defined visible-range absorption is required. The compound is available from manufacturer Carl ROTH for research and industrial laboratory use. Its documented EG number 807-855-6 and clear spectral reference point help laboratories specify and document the reagent consistently across protocols. Use this coumarin derivative wherever a methanol-referenced absorption maximum near 436 nm is specified for VIS-range dye applications.
This article is part of Fluorescent dyes & labels, in Dyes, stains & indicators.

Questions about Coumarin VIS-436 TM-BQZ Et-Ester, Absorption maximum (MeOH) = 436 nm, 1 g, glass
What is this article?
Coumarin VIS-436 TM-BQZ Et-Ester, Absorption maximum (MeOH) = 436 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.
