36877-69-7 Rhodamine isothiocyanate 9-(2-Carboxy-5(or 6)-isothiocyanatophenyl)-3,6-bis(diethylamino)xanthylium chloride Xanthylium, 9-(2-carboxy-5(or 6)-isothiocyanatophenyl)-3,6-bis(diethylamino)-, chloride (1:1) Xanthylium, 9-(2-carboxy-5(or 6)-isothiocyanatophenyl)-3,6-bis(diethylamino)-, chloride EINECS 253-248-9 Rhodamine B isothiocyanate (C29H42N3O3SCl) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
