CATO supplies rel-(4R,4′R,5S,5′S)-2,2′-Ethylidenebis[4,5-dihydro-4,5-diphenyloxazole] (CAS 2035480-66-9), a certified reference material (molecular formula C32H28N2O2, MW 472.58 g/mol) for analytical method development and quality control.
The molecular framework of rel-(4R,4′R,5S,5′S)-2,2′-Ethylidenebis[4,5-dihydro-4,5-diphenyloxazole] (C32H28N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
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.
