Description
As a certified reference material (CRM), 4-Phenyl-3-(trifluoromethyl)-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-Phenyl-3-(trifluoromethyl)-1H-pyrazole (CAS 96256-53-0) is a high-purity analytical reference standard with the molecular formula C10H7F3N2 and a molecular weight of 212.17 g/mol.
4-Phenyl-3-(trifluoromethyl)-1H-pyrazole (C10H7F3N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
