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 (4R,4'R)-2,2'-(1,3-Dihydro-2H-inden-2-ylidene)bis[4,5-dihydro-4-phenyloxazole].
CATO supplies (4R,4'R)-2,2'-(1,3-Dihydro-2H-inden-2-ylidene)bis[4,5-dihydro-4-phenyloxazole] (CAS 2757082-27-0), a certified reference material (molecular formula C27H24N2O2, MW 408.49 g/mol) for analytical method development and quality control.
The molecular framework of (4R,4'R)-2,2'-(1,3-Dihydro-2H-inden-2-ylidene)bis[4,5-dihydro-4-phenyloxazole] (C27H24N2O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
