Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-tert-butyl 2-((1R,2R)-3-(benzyloxy)-1-methoxy-2-methyl-3-oxopropyl)pyrrolidine-1-carboxylate.
CATO supplies (S)-tert-butyl 2-((1R,2R)-3-(benzyloxy)-1-methoxy-2-methyl-3-oxopropyl)pyrrolidine-1-carboxylate (CAS 149606-97-3), a certified reference material (molecular formula C21H31NO5, MW 377.47 g/mol) for analytical method development and quality control.
Structurally, (S)-tert-butyl 2-((1R,2R)-3-(benzyloxy)-1-methoxy-2-methyl-3-oxopropyl)pyrrolidine-1-carboxylate (C21H31NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 377.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
