Chemical Structure

rel-(3R,4S)-3-(4-Chlorophenyl)-4-nitro-1-(phenylmethyl)pyrrolidine CAS 1073263-71-4 chemical structure

Description

The occurrence of rel-(3R,4S)-3-(4-Chlorophenyl)-4-nitro-1-(phenylmethyl)pyrrolidine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies rel-(3R,4S)-3-(4-Chlorophenyl)-4-nitro-1-(phenylmethyl)pyrrolidine (CAS 1073263-71-4), a certified reference material (molecular formula C17H17ClN2O2, MW 316.78 g/mol) for analytical method development and quality control.

rel-(3R,4S)-3-(4-Chlorophenyl)-4-nitro-1-(phenylmethyl)pyrrolidine (C17H17ClN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), rel-(3R,4S)-3-(4-Chlorophenyl)-4-nitro-1-(phenylmethyl)pyrrolidine 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.
