Chemical Structure
Description
5-(4-Bromophenyl)-1-(p-tolyl)-1h-imidazole-2-thiol (CAS 1105189-65-8) is a high-purity analytical reference standard with the molecular formula C16H13BrN2S and a molecular weight of 345.26 g/mol.
The molecular framework of 5-(4-Bromophenyl)-1-(p-tolyl)-1h-imidazole-2-thiol (C16H13BrN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
