(4R,5R,6R)-6-((R)-1,2-diacetoxyethyl)-2-(methoxycarbonyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate CAS 66053-62-1 chemical structure

Description

The occurrence of (4R,5R,6R)-6-((R)-1,2-diacetoxyethyl)-2-(methoxycarbonyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4R,5R,6R)-6-((R)-1,2-diacetoxyethyl)-2-(methoxycarbonyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate (CAS 66053-62-1), molecular formula C19H26O13 and molecular weight 462.40 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4R,5R,6R)-6-((R)-1,2-diacetoxyethyl)-2-(methoxycarbonyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate (C19H26O13) is characterized by a flavonoid core, 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 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 (4R,5R,6R)-6-((R)-1,2-diacetoxyethyl)-2-(methoxycarbonyl)tetrahydro-2H-pyran-2,4,5-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.
