Chemical Structure

3＇-MethoxyPuerarin CAS 117047-07-1 chemical structure

Description

3＇-MethoxyPuerarin (CAS 117047-07-1) is a high-purity analytical reference standard with the molecular formula C22H22O10 and a molecular weight of 446.40 g/mol.

3＇-MethoxyPuerarin (C22H22O10) 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.

As a certified reference material (CRM), 3＇-MethoxyPuerarin 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.
