Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 334.41 g/mol gives (4R,4'R)-2,2'-Methylenebis[4,5-dihydro-4-(phenylmethyl)oxazole] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4R,4'R)-2,2'-Methylenebis[4,5-dihydro-4-(phenylmethyl)oxazole] (CAS 1646862-39-6), molecular formula C21H22N2O2 and molecular weight 334.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4R,4'R)-2,2'-Methylenebis[4,5-dihydro-4-(phenylmethyl)oxazole] (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.
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.
