3-Chloro-2-({7-[(Z)-2-phenylethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}sulfanyl)-5-(trifluoromethyl)pyridine CAS 251096-57-8

Description

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.

CATO supplies 3-Chloro-2-({7-[(Z)-2-phenylethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}sulfanyl)-5-(trifluoromethyl)pyridine (CAS 251096-57-8), a certified reference material (molecular formula C19H11ClF3N5S, MW 433.84 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 3-Chloro-2-({7-[(Z)-2-phenylethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}sulfanyl)-5-(trifluoromethyl)pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 433.84 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).

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.
