tert-Butyl (S)-2-(5-(4-bromophenyl)-1H-imidazol-2-yl)-4,4-difluoropyrrolidine-1-carboxylate CAS 1007882-05-4 chemical structure

Description

The occurrence of tert-Butyl (S)-2-(5-(4-bromophenyl)-1H-imidazol-2-yl)-4,4-difluoropyrrolidine-1-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies tert-Butyl (S)-2-(5-(4-bromophenyl)-1H-imidazol-2-yl)-4,4-difluoropyrrolidine-1-carboxylate (CAS 1007882-05-4), a certified reference material (molecular formula C18H20BrF2N3O2, MW 428.27 g/mol) for analytical method development and quality control.

tert-Butyl (S)-2-(5-(4-bromophenyl)-1H-imidazol-2-yl)-4,4-difluoropyrrolidine-1-carboxylate (C18H20BrF2N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), tert-Butyl (S)-2-(5-(4-bromophenyl)-1H-imidazol-2-yl)-4,4-difluoropyrrolidine-1-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.
