Chemical Structure
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 Phenolphthalein 4′-O-β-D-glucuronide, sodium salt (CAS 6820-54-8), a certified reference material (molecular formula C26H21O10Na, MW 516.43 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Phenolphthalein 4′-O-β-D-glucuronide, sodium salt is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 516.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
