Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

1,1'-(Methylenebis(2,4-dihydroxy-6-methoxy-3,1-phenylene))bis(ethan-1-one) (CAS 142382-28-3), molecular formula C19H20O8 and molecular weight 376.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1'-(Methylenebis(2,4-dihydroxy-6-methoxy-3,1-phenylene))bis(ethan-1-one) (C19H20O8) 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.
