CATO supplies 5-((4-Bromophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbonitrile (CAS 321998-64-5), a certified reference material (molecular formula C17H12BrN3S, MW 370.27 g/mol) for analytical method development and quality control.
5-((4-Bromophenyl)thio)-1-methyl-3-phenyl-1H-pyrazole-4-carbonitrile (C17H12BrN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
