Description
NIR-787 Heptamethine cyanine chloride is a polymethine dye with empirical formula C₃₈H₄₁ClN₂S and CAS number 269401-43-6. This near-infrared cyanine exhibits an absorption maximum of 787 nm in methanol and a molar mass of 593,27 g/mol. The heptamethine cyanine chloride structure supplies a well-characterised framework for studies of optical properties in the near-infrared region. Offered by manufacturer Carl ROTH with EG number 812-345-1, the material fits dye and pigment workflows that require defined absorption around 787 nm for method setup, comparative screening, or formulation work. enables precise handling and is practical for analytical and synthetic laboratories that manage specialised dye quantities for imaging-oriented and optical materials development.
This article is part of Fluorescent dyes & labels, in Dyes, stains & indicators.

Questions about S 0750 - FEW Chemicals, 787 nm in MeOH, 1 g, glass
What is this article?
S 0750 - FEW Chemicals, 787 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.
