2,2′-(4,4′,5,5′-Tetramethyl[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydrooxazole] CAS 1021602-69-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2′-(4,4′,5,5′-Tetramethyl[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydrooxazole].

2,2′-(4,4′,5,5′-Tetramethyl[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydrooxazole] (CAS 1021602-69-6), molecular formula C22H24N2O2 and molecular weight 348.44 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,2′-(4,4′,5,5′-Tetramethyl[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydrooxazole] (C22H24N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 348.44 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′-(4,4′,5,5′-Tetramethyl[1,1′-biphenyl]-2,2′-diyl)bis[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.
