Quercetin-3-O-[α-L-rhamnose-(1→2)-β-D-glucopyranosyl]-5-O-β-D-glucopyranoside CAS 80714-53-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Quercetin-3-O-[α-L-rhamnose-(1→2)-β-D-glucopyranosyl]-5-O-β-D-glucopyranoside.

Quercetin-3-O-[α-L-rhamnose-(1→2)-β-D-glucopyranosyl]-5-O-β-D-glucopyranoside (CAS 80714-53-0), molecular formula C33H40O21 and molecular weight 772.66 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Quercetin-3-O-[α-L-rhamnose-(1→2)-β-D-glucopyranosyl]-5-O-β-D-glucopyranoside (C33H40O21) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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.

CATO manufactures Quercetin-3-O-[α-L-rhamnose-(1→2)-β-D-glucopyranosyl]-5-O-β-D-glucopyranoside 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.
