Description
CATO manufactures 2,2＇-Dihydroxy-4,4＇-dimethoxybenzophenone 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.
2,2＇-Dihydroxy-4,4＇-dimethoxybenzophenone (CAS 131-54-4) is a high-purity analytical reference standard with the molecular formula C15H14O5 and a molecular weight of 274.27 g/mol.
The molecular framework of 2,2＇-Dihydroxy-4,4＇-dimethoxybenzophenone (C15H14O5) 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.
