The occurrence of 2,2′-[1,1′:3′,1′′:3′′,1′′′-Quaterphenyl]-2′,2′′-diylbis[4,5-dihydrooxazole] is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,2′-[1,1′:3′,1′′:3′′,1′′′-Quaterphenyl]-2′,2′′-diylbis[4,5-dihydrooxazole] (CAS 1021602-62-9), a certified reference material (molecular formula C30H24N2O2, MW 444.52 g/mol) for analytical method development and quality control.
Structurally, 2,2′-[1,1′:3′,1′′:3′′,1′′′-Quaterphenyl]-2′,2′′-diylbis[4,5-dihydrooxazole] (C30H24N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 444.52 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), 2,2′-[1,1′:3′,1′′:3′′,1′′′-Quaterphenyl]-2′,2′′-diylbis[4,5-dihydrooxazole] 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.
