Description
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.
CATO supplies 4-[4,5-Dihydro-4-[3-[5-hydroxy-3-methyl-1-(4-sulfophenyl)-1H-pyrazol-4-yl]-2-butenylidene]-3-methyl-5-oxo-1H-pyrazol-1-yl]-benzenesulfonic Acid Tripotassium Salt (CAS 92050-35-6), a certified reference material (molecular formula C24H19N4O8S2K, MW 594.65 g/mol) for analytical method development and quality control.
4-[4,5-Dihydro-4-[3-[5-hydroxy-3-methyl-1-(4-sulfophenyl)-1H-pyrazol-4-yl]-2-butenylidene]-3-methyl-5-oxo-1H-pyrazol-1-yl]-benzenesulfonic Acid Tripotassium Salt (C24H19N4O8S2K) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
