2-(1H-Pyrazol-3-yl)-4-((trifluoromethyl)thio)aniline CAS 1951439-49-8

Description

Compared with other compounds in its class, the molecular weight of 259.25 g/mol gives 2-(1H-Pyrazol-3-yl)-4-((trifluoromethyl)thio)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(1H-Pyrazol-3-yl)-4-((trifluoromethyl)thio)aniline (CAS 1951439-49-8), a certified reference material (molecular formula C10H8F3N3S, MW 259.25 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H8F3N3S, 2-(1H-Pyrazol-3-yl)-4-((trifluoromethyl)thio)aniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 259.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
