Beschrijving
4-Nitrophenyl α-L-arabinofuranoside is een gespecialiseerd biochemisch glycoside met CAS-nummer 6892-58-6 en empirische formule C₁₁H₁₃NO₇. De molaire massa bedraagt 271.22 g/mol, waardoor een betrouwbare berekening van concentraties en molaire equivalenten in laboratoriumprotocollen mogelijk is. De verbinding wordt aangeboden van fabrikant Carl ROTH onder biochemische reagentia voor onderzoeksgerichte werkstromen. Duidelijke registratiegegevens—CAS-nummer, empirische formule en molaire massa—vereenvoudigen specificatiecontroles, veiligheidsdocumentatie en voorraadcodering. De standaard laboratoriumpraktijk omvat koude opslag voor dit materiaal. Al met al biedt dit nitrophenyl arabinofuranoside een goed geïdentificeerd koolhydraatderivaat voor analytische en biochemische toepassingen die een transparante chemische identiteit en een handige verpakkingsgrootte vereisen.

Questions about 4-Nitrophenyl-alpha-L-arabinofuranoside, 250 mg
What is this article?
4-Nitrophenyl-alpha-L-arabinofuranoside, 250 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Fluorescerende kleurstoffen & labels, inside Kleurstoffen, kleuringen & indicatoren, in Chemicaliën.
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.
