Chemical Structure

Biochanin A CAS 491-80-5 chemical structure

Description

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.

Biochanin A (CAS 491-80-5), molecular formula C16H12O5 and molecular weight 284.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Biochanin A is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Biochanin A 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.
