Compared with other compounds in its class, the molecular weight of 564.34 g/mol gives 4-(4-Chlorophenyl)-1-(5-((4-chlorophenyl)thio)-4-(2,4-dichlorophenyl)thiazol-2-yl)-1H-pyrazol-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(4-Chlorophenyl)-1-(5-((4-chlorophenyl)thio)-4-(2,4-dichlorophenyl)thiazol-2-yl)-1H-pyrazol-5-amine (CAS 956738-22-0) is a high-purity analytical reference standard with the molecular formula C24H14Cl4N4S2 and a molecular weight of 564.34 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-(4-Chlorophenyl)-1-(5-((4-chlorophenyl)thio)-4-(2,4-dichlorophenyl)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 564.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
