Description
VIS-586 Trimethine-Cyanine, N-Butyl, N-Ethyl PF₆⁻ is a visible polymethine cyanine dye formulated as the hexafluorophosphate salt with mixed N-butyl and N-ethyl substitution. It carries CAS number 356062-62-9, empirical formula C₃₆H₃₉F₆N₂P and molar mass 644,68 g/mol, and shows an absorption maximum in methanol of 586 nm. The trimethine chain and PF₆ counter-ion define a lipophilic cyanine suitable for laboratory dye chemistry and spectroscopic studies in the orange-red visible region. The article is Absorption data in MeOH support selection of excitation or detection wavelengths near 586 nm during method development. Documented molecular formula and mass enable stoichiometric calculations and identity checks in research workflows. Available from manufacturer Carl ROTH among polymethine dyes, this N-butyl/N-ethyl PF₆ cyanine is intended for professional laboratory handling in accordance with standard chemical safety practice.

Questions about VIS-586 Trimethine-Cyanine, N-Butyl, N-Ethyl PF6-, 1 g, glass
What is this article?
VIS-586 Trimethine-Cyanine, N-Butyl, N-Ethyl PF6-, 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Lab instruments.
A photometer reads absorbance at one or a few wavelengths. A spectrophotometer scans or selects many. Both send light through a cuvette or a well. The wavelength range, UV or visible, and the bandwidth decide what can be measured. A visible-only instrument cannot read a nucleic acid at 260 nm.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
