Chemical Structure

5-Chloro-1-methyl-4-(((perfluorophenyl)thio)methyl)-3-phenyl-1H-pyrazole CAS 956949-82-9 chemical structure

Description

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

5-Chloro-1-methyl-4-(((perfluorophenyl)thio)methyl)-3-phenyl-1H-pyrazole (CAS 956949-82-9) is a high-purity analytical reference standard with the molecular formula C17H10ClF5N2S and a molecular weight of 404.78 g/mol.

5-Chloro-1-methyl-4-(((perfluorophenyl)thio)methyl)-3-phenyl-1H-pyrazole (C17H10ClF5N2S) 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).

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.
