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 1-((3S,4R)-3-Hydroxy-2,2-dimethyl-6-(phenylsulfonyl)chroman-4-yl)pyrrolidin-2-one (CAS 132014-21-2), a certified reference material (molecular formula C21H23NO5S, MW 401.48 g/mol) for analytical method development and quality control.
1-((3S,4R)-3-Hydroxy-2,2-dimethyl-6-(phenylsulfonyl)chroman-4-yl)pyrrolidin-2-one (C21H23NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
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.
