4-(4-Fluorophenyl)-1-(4-(3-fluorophenyl)thiazol-2-yl)-1H-pyrazol-5-amine CAS 955976-89-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 4-(4-Fluorophenyl)-1-(4-(3-fluorophenyl)thiazol-2-yl)-1H-pyrazol-5-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

CATO supplies 4-(4-Fluorophenyl)-1-(4-(3-fluorophenyl)thiazol-2-yl)-1H-pyrazol-5-amine (CAS 955976-89-3), a certified reference material (molecular formula C18H12F2N4S, MW 354.38 g/mol) for analytical method development and quality control.

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.
