2-(3,5-dihydroxyphenyl)-3,6,8-trihydroxy-1-benzopyran-4-one 2-[3,5-bis(oxidanyl)phenyl]-3,6,8-tris(oxidanyl)chromen-4-one 4894-75-1 A827634 (CAS 4894-75-1), molecular formula C12H20O and molecular weight 180.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(3,5-dihydroxyphenyl)-3,6,8-trihydroxy-1-benzopyran-4-one 2-[3,5-bis(oxidanyl)phenyl]-3,6,8-tris(oxidanyl)chromen-4-one 4894-75-1 A827634 (C12H20O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
