Description
NIR-997 Heptamethine Cyanine BF4 is a near-infrared polymethine dye with CAS number 1289375-50-3 and empirical formula C₄₆H₄₅BF₄N₂. This heptamethine cyanine tetrafluoroborate displays an absorption maximum of 997 nm in methanol and a molar mass of 712,68 g/mol. It is Belonging to the polymethine dye family, the compound provides a defined NIR absorption profile for spectroscopic measurements and dye-chemistry work. Laboratories obtain this characterised cyanine from manufacturer Carl ROTH under EG number 812-695-5. The combination of molecular formula, molar mass and absorption maximum supports selection where a heptamethine structure active near 997 nm is needed. Whether applied in optical studies, method development or comparative dye experiments, the material offers clear identity data for controlled laboratory settings. Packaged for practical handling, NIR-997 Heptamethine Cyanine BF4 is a useful option for research groups working with cyanine and polymethine dye systems in the near-infrared spectral range around 997 nm.

Questions about S 0889 - FEW Chemicals, 997 nm in MeOH, 1 g, glass
What is this article?
S 0889 - FEW Chemicals, 997 nm in MeOH, 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.
