Chemical Structure

Quercetin-4 '- O-glucuronide CAS 201463-36-7 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 Quercetin-4 '- O-glucuronide.

Quercetin-4 '- O-glucuronide (CAS 201463-36-7), molecular formula C21H18O13 and molecular weight 478.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Quercetin-4 '- O-glucuronide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 478.36 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 Quercetin-4 '- O-glucuronide 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.
