Chemical Structure

(3S,4R)-4-(2,5-Dichlorophenyl)pyrrolidine-3-carboxylic acid CAS 1049978-45-1 chemical structure

Description

The occurrence of (3S,4R)-4-(2,5-Dichlorophenyl)pyrrolidine-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3S,4R)-4-(2,5-Dichlorophenyl)pyrrolidine-3-carboxylic acid (CAS 1049978-45-1), molecular formula C11H11Cl2NO2 and molecular weight 260.12 g/mol, is a CATO reference standard with documented purity and traceability.

(3S,4R)-4-(2,5-Dichlorophenyl)pyrrolidine-3-carboxylic acid (C11H11Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (3S,4R)-4-(2,5-Dichlorophenyl)pyrrolidine-3-carboxylic acid 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.
