Chemical Structure
Description
3-[2-(3-methylphenyl)pyrrolidine-1-carbonyl]-5-(propan-2-yl)-1,2-oxazole (CAS 1031585-85-9), molecular formula C18H22N2O2 and molecular weight 298.38 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, 3-[2-(3-methylphenyl)pyrrolidine-1-carbonyl]-5-(propan-2-yl)-1,2-oxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.38 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.
CATO manufactures 3-[2-(3-methylphenyl)pyrrolidine-1-carbonyl]-5-(propan-2-yl)-1,2-oxazole 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.
