Description
CATO manufactures (4S,4′S)-2,2′-Dicyclohexyl-4,4′,5,5′-tetrahydro-4,4′-bioxazole 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.
(4S,4′S)-2,2′-Dicyclohexyl-4,4′,5,5′-tetrahydro-4,4′-bioxazole (CAS 263752-10-9) is a high-purity analytical reference standard with the molecular formula C18H28N2O2 and a molecular weight of 304.43 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (4S,4′S)-2,2′-Dicyclohexyl-4,4′,5,5′-tetrahydro-4,4′-bioxazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.43 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
