Description

As a certified reference material (CRM), 23405-70-1 3-Hydroxy-5,7-bis(phenylmethoxy)-2-[4-(phenylmethoxy)phenyl]-4H-1-benzopyran-4-one 4',5,7-Tris(benzyloxy)-3-hydroxy-flavone 5,7-Bis-(benzyloxy)-2-(4-(benzyloxy)phenyl)-3-hydroxy-4H-chromen-4-one 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.

23405-70-1 3-Hydroxy-5,7-bis(phenylmethoxy)-2-[4-(phenylmethoxy)phenyl]-4H-1-benzopyran-4-one 4',5,7-Tris(benzyloxy)-3-hydroxy-flavone 5,7-Bis-(benzyloxy)-2-(4-(benzyloxy)phenyl)-3-hydroxy-4H-chromen-4-one (CAS 23405-70-1) is a high-purity analytical reference standard with the molecular formula C36H28O6 and a molecular weight of 556.60 g/mol.

23405-70-1 3-Hydroxy-5,7-bis(phenylmethoxy)-2-[4-(phenylmethoxy)phenyl]-4H-1-benzopyran-4-one 4',5,7-Tris(benzyloxy)-3-hydroxy-flavone 5,7-Bis-(benzyloxy)-2-(4-(benzyloxy)phenyl)-3-hydroxy-4H-chromen-4-one (C36H28O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
