(R)-Phenyl 3-O-[(4-methoxyphenyl)methyl]-4,6-O-(phenylmethylene)-1-thio-alpha-D-mannopyranoside CAS 168138-26-9 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 (R)-Phenyl 3-O-[(4-methoxyphenyl)methyl]-4,6-O-(phenylmethylene)-1-thio-alpha-D-mannopyranoside.

CATO supplies (R)-Phenyl 3-O-[(4-methoxyphenyl)methyl]-4,6-O-(phenylmethylene)-1-thio-alpha-D-mannopyranoside (CAS 168138-26-9), a certified reference material (molecular formula C27H28O6S, MW 480.57 g/mol) for analytical method development and quality control.

The molecular framework of (R)-Phenyl 3-O-[(4-methoxyphenyl)methyl]-4,6-O-(phenylmethylene)-1-thio-alpha-D-mannopyranoside (C27H28O6S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.

As a certified reference material (CRM), (R)-Phenyl 3-O-[(4-methoxyphenyl)methyl]-4,6-O-(phenylmethylene)-1-thio-alpha-D-mannopyranoside meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
