Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4R,4'R)-2,2'-Cyclohexylidenebis[4-tert-butyl-4,5-dihydrooxazole].
CATO supplies (4R,4'R)-2,2'-Cyclohexylidenebis[4-tert-butyl-4,5-dihydrooxazole] (CAS 2757082-26-9), a certified reference material (molecular formula C20H34N2O2, MW 334.50 g/mol) for analytical method development and quality control.
The molecular framework of (4R,4'R)-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (4R,4'R)-2,2'-Cyclohexylidenebis[4-tert-butyl-4,5-dihydrooxazole] under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
