Chemical Structure
Description
As a certified reference material (CRM), Ethyl 1-benzyl-4-(4-bromophenyl)pyrrolidine-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Ethyl 1-benzyl-4-(4-bromophenyl)pyrrolidine-3-carboxylate (CAS 885959-02-4), molecular formula C20H22BrNO2 and molecular weight 388.30 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, bromine substitution, Ethyl 1-benzyl-4-(4-bromophenyl)pyrrolidine-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.30 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.
