8-Bromo-4-chloro-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazine (CAS 54346-33-7) is a high-purity analytical reference standard with the molecular formula C6H4BrClN4S and a molecular weight of 279.54 g/mol.
Owing to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, 8-Bromo-4-chloro-2-(methylthio)pyrazolo[1,5-a][1,3,5]triazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.54 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).
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.
