CATO supplies 5-Amino-1-(4-bromophenyl)-1H-pyrazole-4-carbonitrile (CAS 5334-28-1), a certified reference material (molecular formula C10H7BrN4, MW 263.09 g/mol) for analytical method development and quality control.
5-Amino-1-(4-bromophenyl)-1H-pyrazole-4-carbonitrile (C10H7BrN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
