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 (3aS,3'aS,8aR,8'aR)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole].
CATO supplies (3aS,3'aS,8aR,8'aR)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] (CAS 1091605-95-6), a certified reference material (molecular formula C22H20N2O2, MW 344.41 g/mol) for analytical method development and quality control.
(3aS,3'aS,8aR,8'aR)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] (C22H20N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures (3aS,3'aS,8aR,8'aR)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] 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.
