Chemical Structure
Description
The occurrence of (4R,4'R)-2,2'-(1,3-Dihydro-2H-inden-2-ylidene)bis[4,5-dihydro-4-(phenylmethyl)oxazole] is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4R,4'R)-2,2'-(1,3-Dihydro-2H-inden-2-ylidene)bis[4,5-dihydro-4-(phenylmethyl)oxazole] (CAS 2757082-00-9), molecular formula C29H28N2O2 and molecular weight 436.54 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4R,4'R)-2,2'-(1,3-Dihydro-2H-inden-2-ylidene)bis[4,5-dihydro-4-(phenylmethyl)oxazole] (C29H28N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 436.54 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
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.
