(3aS,6R,7aS)-6-Ethyl-1-oxo-2,3,3a,6,7,7a-hexahydro-1H-indene-4-carboxylic acid (CAS 62251-98-3) is a high-purity analytical reference standard with the molecular formula C12H16O3 and a molecular weight of 208.25 g/mol.
(3aS,6R,7aS)-6-Ethyl-1-oxo-2,3,3a,6,7,7a-hexahydro-1H-indene-4-carboxylic acid (C12H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures (3aS,6R,7aS)-6-Ethyl-1-oxo-2,3,3a,6,7,7a-hexahydro-1H-indene-4-carboxylic acid 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.
