Description
Compared with other compounds in its class, the molecular weight of 334.50 g/mol gives (4S,4'S)-2,2'-Cyclohexylidenebis[4-tert-butyl-4,5-dihydrooxazole] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (4S,4'S)-2,2'-Cyclohexylidenebis[4-tert-butyl-4,5-dihydrooxazole] (CAS 298693-04-6), a certified reference material (molecular formula C20H34N2O2, MW 334.50 g/mol) for analytical method development and quality control.
The molecular framework of (4S,4'S)-2,2'-Cyclohexylidenebis[4-tert-butyl-4,5-dihydrooxazole] (C20H34N2O2) 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.
As a certified reference material (CRM), (4S,4'S)-2,2'-Cyclohexylidenebis[4-tert-butyl-4,5-dihydrooxazole] meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
