Chemical Structure
Description
Emodin 8-O-(6′-methylmalonyl)-glucopyranoside (CAS 928262-58-2) is a high-purity analytical reference standard with the molecular formula C24H22O13 and a molecular weight of 518.42 g/mol.
The molecular framework of Emodin 8-O-(6′-methylmalonyl)-glucopyranoside (C24H22O13) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Emodin 8-O-(6′-methylmalonyl)-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.
