(4S,4'S)-2,2'-Cyclopentylidenebis[4-tert-butyl-4,5-dihydrooxazole] CAS 298693-03-5

Description

The occurrence of (4S,4'S)-2,2'-Cyclopentylidenebis[4-tert-butyl-4,5-dihydrooxazole] 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.

(4S,4'S)-2,2'-Cyclopentylidenebis[4-tert-butyl-4,5-dihydrooxazole] (CAS 298693-03-5), molecular formula C19H32N2O2 and molecular weight 320.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4S,4'S)-2,2'-Cyclopentylidenebis[4-tert-butyl-4,5-dihydrooxazole] (C19H32N2O2) 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).

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.
