CATO supplies 5-Amino-3-(4-chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 873913-39-4), a certified reference material (molecular formula C16H12ClN3O, MW 297.74 g/mol) for analytical method development and quality control.
5-Amino-3-(4-chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (C16H12ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
