Chemical Structure
Description
The molecular framework of 5-Phenyl-1-(2,2,2-trifluoroethyl)-1h-imidazole-2-thiol (C11H9F3N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5-Phenyl-1-(2,2,2-trifluoroethyl)-1h-imidazole-2-thiol (CAS 1094354-75-2) is a high-purity analytical reference standard with the molecular formula C11H9F3N2S and a molecular weight of 258.26 g/mol.
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.
