Description

Oxazole, 2,2′-[oxybis(methylene)]bis[4,5-dihydro-5-methyl-4-phenyl-, (4R,4′R,5R,5′R)- (CAS 474364-68-6) is a high-purity analytical reference standard with the molecular formula C22H24N2O3 and a molecular weight of 364.44 g/mol.

The molecular framework of Oxazole, 2,2′-[oxybis(methylene)]bis[4,5-dihydro-5-methyl-4-phenyl-, (4R,4′R,5R,5′R)- (C22H24N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Oxazole, 2,2′-[oxybis(methylene)]bis[4,5-dihydro-5-methyl-4-phenyl-, (4R,4′R,5R,5′R)- 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.
