Beschreibung
VIS-586 Trimethine-cyanine, N-butyl, N-ethyl PF₆⁻ is een zichtbare polymethine-cyaninekleurstof geformuleerd als het hexafluorfosfaatzout met gemengde N-butyl- en N-ethyl-substitutie. Het heeft CAS-nummer 356062-62-9, de brutoformule C₃₆H₃₉F₆N₂P en een molaire massa van 644,68 g/mol, en vertoont een absorptiemaximum in methanol van 586 nm. De trimethineketen en het PF₆-tegenion definiëren een lipofiele cyanine die geschikt is voor laboratoriumkleurstofchemie en spectroscopische studies in het oranje-rode zichtbare gebied. De absorptiegegevens in MeOH ondersteunen de selectie van excitatie- of detectiegolflengten nabij 586 nm tijdens de methodeontwikkeling. De gedocumenteerde molecuulformule en massa maken stoichiometrische berekeningen en identiteitscontroles in onderzoeksworkflows mogelijk. Deze N-butyl/N-ethyl PF₆-cyanine is verkrijgbaar bij fabrikant Carl ROTH in de categorie polymethinekleurstoffen en is bedoeld voor professioneel laboratoriumgebruik in overeenstemming met de standaard chemische veiligheidspraktijken.
Dit artikel hoort bij Fotometers & spectrofotometers, in Spectroscopie & fotometrie.

Questions about VIS-586 Trimethine-cyanine, N-butyl, N-ethyl PF6-, 1 g, glas
What is this article?
VIS-586 Trimethine-cyanine, N-butyl, N-ethyl PF6-, 1 g, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Präzisionsinstrumente.
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.
Which category should I open next?
