Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-(4R,4′S)-2,2′-(1-Methylethylidene)bis[4,5-dihydro-4-phenyloxazole].

rel-(4R,4′S)-2,2′-(1-Methylethylidene)bis[4,5-dihydro-4-phenyloxazole] (CAS 262439-02-1) is a high-purity analytical reference standard with the molecular formula C21H22N2O2 and a molecular weight of 334.41 g/mol.

The molecular framework of rel-(4R,4′S)-2,2′-(1-Methylethylidene)bis[4,5-dihydro-4-phenyloxazole] (C21H22N2O2) 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 its high hydrophobicity (logP), 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), rel-(4R,4′S)-2,2′-(1-Methylethylidene)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.
