Beschreibung
Coumarine VIS-438 Diethylamino-benzimidazool is een coumarinekleurstof met de brutoformule C₂₀H₁₉N₃O₂, CAS-nummer 27425-55-4 en een molaire massa van 333,39 g/mol. Gemeten in methanol is het absorptiemaximum 438 nm, waardoor de chromofoor zich duidelijk in het zichtbare bereik bevindt voor spectroscopische en kleurstofapplicaties. Het is geregistreerd onder EG-nr. 248-451-4 en de identiteits- en optische gegevens van fabrikant Carl ROTH ondersteunen een reproduceerbare selectie van deze diethylamino-benzimidazool-coumarine in onderzoeksworkflows. De gedefinieerde molaire massa en het absorptiemaximum ondersteunen kalibratie, spectrale vergelijking en methodeontwikkeling met betrekking tot kleurstoffen van het coumarine-type. De hoeveelheid is praktisch voor screening, follow-up van kleinschalige synthese en de bereiding van referentievoorraden. Duidelijke etikettering van CAS, EG en formule vereenvoudigt voorraadbeheer en documentatie in laboratoria voor analyse, materialen en fotochemie die werken met in het zichtbare spectrum absorberende organische kleurstoffen.
Dit artikel behoort tot Fluorescerende kleurstoffen & labels, in Kleurstoffen, vloeistoffen & indicatoren.

Questions about Coumarine VIS-438, Diethylamino Benzimidazol, 1 g, glas
What is this article?
Coumarine VIS-438, Diethylamino Benzimidazol, 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.
