Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 810.39 g/mol gives Methyl (3S,4R,5S,6R)-5-acetamido-4-(benzyloxy)-2-chloro-3-(phenylthio)-6-((1S,2R)-1,2,3-tris(benzyloxy)propyl)tetrahydro-2H-pyran-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl (3S,4R,5S,6R)-5-acetamido-4-(benzyloxy)-2-chloro-3-(phenylthio)-6-((1S,2R)-1,2,3-tris(benzyloxy)propyl)tetrahydro-2H-pyran-2-carboxylate (CAS 120308-52-3), a certified reference material (molecular formula C46H48ClNO8S, MW 810.39 g/mol) for analytical method development and quality control.
The molecular framework of Methyl (3S,4R,5S,6R)-5-acetamido-4-(benzyloxy)-2-chloro-3-(phenylthio)-6-((1S,2R)-1,2,3-tris(benzyloxy)propyl)tetrahydro-2H-pyran-2-carboxylate (C46H48ClNO8S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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.
