Potassium 2-(3-(1-(6-((2,5-dioxopyrrolidin-1-yl)oxy)-6-oxohexyl)-3,3-dimethyl-5-sulfonatoindolin-2-ylidene)prop-1-en-1-yl)-1-ethyl-3,3-dimethyl-3H-indol-1-ium-5-sulfonate (CAS 945529-56-6) is a high-purity analytical reference standard with the molecular formula C35H40N3O10S2K and a molecular weight of 765.93 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Potassium 2-(3-(1-(6-((2,5-dioxopyrrolidin-1-yl)oxy)-6-oxohexyl)-3,3-dimethyl-5-sulfonatoindolin-2-ylidene)prop-1-en-1-yl)-1-ethyl-3,3-dimethyl-3H-indol-1-ium-5-sulfonate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 765.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
