Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(4S)-2-[1,1′-Biphenyl]-2-yl-4,5-dihydro-4-phenyloxazole (CAS 1808153-10-7), molecular formula C21H17NO and molecular weight 299.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (4S)-2-[1,1′-Biphenyl]-2-yl-4,5-dihydro-4-phenyloxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures (4S)-2-[1,1′-Biphenyl]-2-yl-4,5-dihydro-4-phenyloxazole 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.
