4-(((4-Bromophenyl)thio)methyl)-5-chloro-3-(((4-chlorophenyl)thio)methyl)-1-methyl-1H-pyrazole CAS 318234-31-0 chemical structure

Description

The occurrence of 4-(((4-Bromophenyl)thio)methyl)-5-chloro-3-(((4-chlorophenyl)thio)methyl)-1-methyl-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(((4-Bromophenyl)thio)methyl)-5-chloro-3-(((4-chlorophenyl)thio)methyl)-1-methyl-1H-pyrazole (CAS 318234-31-0) is a high-purity analytical reference standard with the molecular formula C18H15BrCl2N2S2 and a molecular weight of 474.27 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, 4-(((4-Bromophenyl)thio)methyl)-5-chloro-3-(((4-chlorophenyl)thio)methyl)-1-methyl-1H-pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 474.27 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).

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.
