Chemical Structure
Description
The occurrence of (4S,5R)-N-(4-Bromophenyl)-3-oxo-4,5-diphenylpyrazolidine-1-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4S,5R)-N-(4-Bromophenyl)-3-oxo-4,5-diphenylpyrazolidine-1-carboxamide (CAS 147523-65-7), molecular formula C22H18BrN3O2 and molecular weight 436.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4S,5R)-N-(4-Bromophenyl)-3-oxo-4,5-diphenylpyrazolidine-1-carboxamide (C22H18BrN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
