Chemical Structure

5-Chloro-3-(((4-chlorophenyl)thio)methyl)-4-(((4-fluorophenyl)thio)methyl)-1-methyl-1H-pyrazole CAS 318234-41-2 chemical structure

Description

5-Chloro-3-(((4-chlorophenyl)thio)methyl)-4-(((4-fluorophenyl)thio)methyl)-1-methyl-1H-pyrazole (C18H15Cl2FN2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

5-Chloro-3-(((4-chlorophenyl)thio)methyl)-4-(((4-fluorophenyl)thio)methyl)-1-methyl-1H-pyrazole (CAS 318234-41-2), molecular formula C18H15Cl2FN2S2 and molecular weight 413.36 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 5-Chloro-3-(((4-chlorophenyl)thio)methyl)-4-(((4-fluorophenyl)thio)methyl)-1-methyl-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.
