Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 446.36 g/mol gives Rhein 8-Glucoside distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rhein 8-Glucoside (CAS 34298-86-7), molecular formula C21H18O11 and molecular weight 446.36 g/mol, is a CATO reference standard with documented purity and traceability.
Rhein 8-Glucoside (C21H18O11) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 Rhein 8-Glucoside 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.
