Chemical Structure
Description
(2R,3R,4R,5S,6S)-2-(acetoxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 51897-78-0), molecular formula C15H22O10 and molecular weight 362.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,3R,4R,5S,6S)-2-(acetoxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (2R,3R,4R,5S,6S)-2-(acetoxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate 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.
