Description

CATO manufactures (2R,3R,4S,5R,6S)-4,5-Bis(benzyloxy)-2-(hydroxymethyl)-6-(phenylthio)tetrahydro-2H-pyran-3-ol 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.

CATO supplies (2R,3R,4S,5R,6S)-4,5-Bis(benzyloxy)-2-(hydroxymethyl)-6-(phenylthio)tetrahydro-2H-pyran-3-ol (CAS 129081-01-2), a certified reference material (molecular formula C26H28O5S, MW 452.56 g/mol) for analytical method development and quality control.

Structurally, (2R,3R,4S,5R,6S)-4,5-Bis(benzyloxy)-2-(hydroxymethyl)-6-(phenylthio)tetrahydro-2H-pyran-3-ol (C26H28O5S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 452.56 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
