Chemical Structure
Description
The molecular framework of Caffeic acid 3-O-β-D-glucuronide (C15H16O10) 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 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).
Caffeic acid 3-O-β-D-glucuronide (CAS 1093679-73-2) is a high-purity analytical reference standard with the molecular formula C15H16O10 and a molecular weight of 356.28 g/mol.
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.
As a certified reference material (CRM), Caffeic acid 3-O-β-D-glucuronide 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.
