(3aR,3'aR,8aS,8'aS)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] CAS 950596-31-3 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 (3aR,3'aR,8aS,8'aS)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole].

CATO supplies (3aR,3'aR,8aS,8'aS)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] (CAS 950596-31-3), a certified reference material (molecular formula C22H20N2O2, MW 344.41 g/mol) for analytical method development and quality control.

Based on its molecular formula C22H20N2O2, (3aR,3'aR,8aS,8'aS)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 344.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), (3aR,3'aR,8aS,8'aS)-2,2'-Ethylidenebis[3a,8a-dihydro-8H-indeno[1,2-d]oxazole] 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.
