Chemical Structure
Description
4-(5-(4-Methoxyphenyl)oxazol-2-yl)-9H-fluoren-9-one (CAS 313367-92-9) is a high-purity analytical reference standard with the molecular formula C23H15NO3 and a molecular weight of 353.37 g/mol.
4-(5-(4-Methoxyphenyl)oxazol-2-yl)-9H-fluoren-9-one (C23H15NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 4-(5-(4-Methoxyphenyl)oxazol-2-yl)-9H-fluoren-9-one 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.
