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 (2S,3R,4S,5R,6R)-6-((benzyloxy)methyl)-2-(ethylthio)-5-hydroxytetrahydro-2H-pyran-3,4-diyl dibenzoate.
(2S,3R,4S,5R,6R)-6-((benzyloxy)methyl)-2-(ethylthio)-5-hydroxytetrahydro-2H-pyran-3,4-diyl dibenzoate (CAS 149521-64-2) is a high-purity analytical reference standard with the molecular formula C29H30O7S and a molecular weight of 522.61 g/mol.
(2S,3R,4S,5R,6R)-6-((benzyloxy)methyl)-2-(ethylthio)-5-hydroxytetrahydro-2H-pyran-3,4-diyl dibenzoate (C29H30O7S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
