Description

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.

(4S,4′S)-2,2′-(5,5′-Dimethoxy[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydro-4-phenyloxazole] (CAS 944133-17-9), molecular formula C32H28N2O4 and molecular weight 504.58 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (4S,4′S)-2,2′-(5,5′-Dimethoxy[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydro-4-phenyloxazole] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 504.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), (4S,4′S)-2,2′-(5,5′-Dimethoxy[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydro-4-phenyloxazole] 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.
