Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4AS,7aS)-4-((R)-1-phenylethyl)-6-tosylhexahydro-pyrrolo[3,4-b][1,4]oxazin-3(2H)-one.
CATO supplies (4AS,7aS)-4-((R)-1-phenylethyl)-6-tosylhexahydro-pyrrolo[3,4-b][1,4]oxazin-3(2H)-one (CAS 1159908-20-9), a certified reference material (molecular formula C21H24N2O4S, MW 400.49 g/mol) for analytical method development and quality control.
The molecular framework of (4AS,7aS)-4-((R)-1-phenylethyl)-6-tosylhexahydro-pyrrolo[3,4-b][1,4]oxazin-3(2H)-one (C21H24N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (4AS,7aS)-4-((R)-1-phenylethyl)-6-tosylhexahydro-pyrrolo[3,4-b][1,4]oxazin-3(2H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
