As a certified reference material (CRM), 3-Butyryl-4-hydroxy-3'-phenoxy-5,6-dihydro-[1,1'-biphenyl]-2(1H)-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.
3-Butyryl-4-hydroxy-3'-phenoxy-5,6-dihydro-[1,1'-biphenyl]-2(1H)-one (CAS 866153-77-7), molecular formula C22H22O4 and molecular weight 350.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 3-Butyryl-4-hydroxy-3'-phenoxy-5,6-dihydro-[1,1'-biphenyl]-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
