Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-PREGNEN-17, 21-DIOL-3, 11, 20-TRIONE 21-SULPHATE, SODIUM SALT (CAS 112925-31-2), a certified reference material (molecular formula C21H27O8SNa, MW 462.49 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, 4-PREGNEN-17, 21-DIOL-3, 11, 20-TRIONE 21-SULPHATE, SODIUM SALT is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.49 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).
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.
