Chemical Structure
Description
The occurrence of 4,4'-Diisothiocyano-2,2'-dihydrostilbenedisulfonic Acid Disodium Salt is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,4'-Diisothiocyano-2,2'-dihydrostilbenedisulfonic Acid Disodium Salt (CAS 150321-88-3), a certified reference material (molecular formula C16H10N2O6S4Na, MW 477.49 g/mol) for analytical method development and quality control.
4,4'-Diisothiocyano-2,2'-dihydrostilbenedisulfonic Acid Disodium Salt (C16H10N2O6S4Na) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
