Chemical Structure
Description
The occurrence of 5-Chloro-4-{[(2,5-dichlorophenyl)sulfanyl]methyl}-1-methyl-3-phenyl-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-4-{[(2,5-dichlorophenyl)sulfanyl]methyl}-1-methyl-3-phenyl-1H-pyrazole (CAS 956795-51-0), molecular formula C17H13Cl3N2S and molecular weight 383.72 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-4-{[(2,5-dichlorophenyl)sulfanyl]methyl}-1-methyl-3-phenyl-1H-pyrazole (C17H13Cl3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 5-Chloro-4-{[(2,5-dichlorophenyl)sulfanyl]methyl}-1-methyl-3-phenyl-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
