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 8H-Indeno[1,2-d]oxazole, 2,2′-(1,3-phenylene)bis[3a,8a-dihydro-, [3aS-[2(3′aR*,8′aS*),3aα,8aα]]-.
CATO supplies 8H-Indeno[1,2-d]oxazole, 2,2′-(1,3-phenylene)bis[3a,8a-dihydro-, [3aS-[2(3′aR*,8′aS*),3aα,8aα]]- (CAS 175733-74-1), a certified reference material (molecular formula C26H20N2O2, MW 392.45 g/mol) for analytical method development and quality control.
8H-Indeno[1,2-d]oxazole, 2,2′-(1,3-phenylene)bis[3a,8a-dihydro-, [3aS-[2(3′aR*,8′aS*),3aα,8aα]]- (C26H20N2O2) 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.
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 8H-Indeno[1,2-d]oxazole, 2,2′-(1,3-phenylene)bis[3a,8a-dihydro-, [3aS-[2(3′aR*,8′aS*),3aα,8aα]]- 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.
