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 5-Iodoresorcinol-2',3',4'-tri-O-acetyl-β-D-glucuronide Methyl Ester.
5-Iodoresorcinol-2',3',4'-tri-O-acetyl-β-D-glucuronide Methyl Ester (CAS 490028-20-1), molecular formula C19H21IO11 and molecular weight 552.27 g/mol, is a CATO reference standard with documented purity and traceability.
5-Iodoresorcinol-2',3',4'-tri-O-acetyl-β-D-glucuronide Methyl Ester (C19H21IO11) contains a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 5-Iodoresorcinol-2',3',4'-tri-O-acetyl-β-D-glucuronide Methyl Ester 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.
