Chemical Structure
Description
As a certified reference material (CRM), Methyl 1-benzyl-4-(4-chlorophenyl)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.
CATO supplies Methyl 1-benzyl-4-(4-chlorophenyl)pyrrolidine-3-carboxylate (CAS 438492-34-3), a certified reference material (molecular formula C19H20ClNO2, MW 329.82 g/mol) for analytical method development and quality control.
Methyl 1-benzyl-4-(4-chlorophenyl)pyrrolidine-3-carboxylate (C19H20ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
