Chemical Structure

Desmethyl Icaritin CAS 28610-31-3 chemical structure

Description

Desmethyl Icaritin (CAS 28610-31-3), molecular formula C20H18O6 and molecular weight 354.35 g/mol, is a CATO reference standard with documented purity and traceability.

Desmethyl Icaritin (C20H18O6) 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.

CATO manufactures Desmethyl Icaritin 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.
