Chemical Structure

11-O-Galloylbergenin CAS 82958-44-9 chemical structure

Description

As a certified reference material (CRM), 11-O-Galloylbergenin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

11-O-Galloylbergenin (CAS 82958-44-9), molecular formula C21H20O13 and molecular weight 480.38 g/mol, is a CATO reference standard with documented purity and traceability.

11-O-Galloylbergenin (C21H20O13) 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 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.
