(2R,3R)-3,5,7-Trihydroxy-2-(4-hydroxy-3-methoxyphenyl)chroman-4-one CAS 55812-91-4 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 (2R,3R)-3,5,7-Trihydroxy-2-(4-hydroxy-3-methoxyphenyl)chroman-4-one.

(2R,3R)-3,5,7-Trihydroxy-2-(4-hydroxy-3-methoxyphenyl)chroman-4-one (CAS 55812-91-4), molecular formula C16H14O7 and molecular weight 318.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2R,3R)-3,5,7-Trihydroxy-2-(4-hydroxy-3-methoxyphenyl)chroman-4-one (C16H14O7) 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 (2R,3R)-3,5,7-Trihydroxy-2-(4-hydroxy-3-methoxyphenyl)chroman-4-one 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.
