Chemical Structure
Description
The molecular framework of (S)-5-(4-Bromophenyl)-2-(pyrrolidin-2-yl)-1H-imidazole (C13H14BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
(S)-5-(4-Bromophenyl)-2-(pyrrolidin-2-yl)-1H-imidazole (CAS 1255936-24-3), molecular formula C13H14BrN3 and molecular weight 292.17 g/mol, is a CATO reference standard with documented purity and traceability.
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 (S)-5-(4-Bromophenyl)-2-(pyrrolidin-2-yl)-1H-imidazole 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.
