(4S,4′S)-4,4′-Dicyclohexyl-4,4′,5,5′-tetrahydro-2,2′-bioxazole CAS 2368835-34-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4S,4′S)-4,4′-Dicyclohexyl-4,4′,5,5′-tetrahydro-2,2′-bioxazole.

(4S,4′S)-4,4′-Dicyclohexyl-4,4′,5,5′-tetrahydro-2,2′-bioxazole (CAS 2368835-34-9), molecular formula C18H28N2O2 and molecular weight 304.43 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4S,4′S)-4,4′-Dicyclohexyl-4,4′,5,5′-tetrahydro-2,2′-bioxazole (C18H28N2O2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
