CATO supplies 5-((4-Bromophenyl)thio)-1,3-diphenyl-1H-pyrazole-4-carbaldehyde (CAS 956183-52-1), a certified reference material (molecular formula C22H15BrN2OS, MW 435.34 g/mol) for analytical method development and quality control.
5-((4-Bromophenyl)thio)-1,3-diphenyl-1H-pyrazole-4-carbaldehyde (C22H15BrN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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 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.
