Chemical Structure
Description
CATO supplies 1-(4-Bromophenyl)-3-((4-chlorophenyl)thio)pyrrolidine-2,5-dione (CAS 326920-95-0), a certified reference material (molecular formula C16H11BrClNO2S, MW 396.69 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Bromophenyl)-3-((4-chlorophenyl)thio)pyrrolidine-2,5-dione (C16H11BrClNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 1-(4-Bromophenyl)-3-((4-chlorophenyl)thio)pyrrolidine-2,5-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
