Chemical Structure
Description
4-chloro-2-(methylsulfanyl)-5-(trifluoromethyl)aniline hydrochloride (CAS 1989659-10-0) is a high-purity analytical reference standard with the molecular formula C8H7ClF3NSHCl and a molecular weight of 278.11 g/mol.
The molecular framework of 4-chloro-2-(methylsulfanyl)-5-(trifluoromethyl)aniline hydrochloride (C8H7ClF3NSHCl) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
