Chemical Structure

2,3-Dehydrosilybin A CAS 25166-14-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 480.42 g/mol gives 2,3-Dehydrosilybin A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3-Dehydrosilybin A (CAS 25166-14-7) is a high-purity analytical reference standard with the molecular formula C25H20O10 and a molecular weight of 480.42 g/mol.

The molecular framework of 2,3-Dehydrosilybin A (C25H20O10) 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).

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 2,3-Dehydrosilybin A 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.
