Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3R,4R,5R,6R)-2-(Acetoxymethyl)-6-((trimethylsilyl)ethynyl)tetrahydro-2h-pyran-3,4,5-triyl triacetate.
(2R,3R,4R,5R,6R)-2-(Acetoxymethyl)-6-((trimethylsilyl)ethynyl)tetrahydro-2h-pyran-3,4,5-triyl triacetate (CAS 849359-20-2), molecular formula C19H28O9Si and molecular weight 428.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R,3R,4R,5R,6R)-2-(Acetoxymethyl)-6-((trimethylsilyl)ethynyl)tetrahydro-2h-pyran-3,4,5-triyl triacetate (C19H28O9Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
