Chemical Structure
Description
1-Phenyl-3-(trifluoromethyl)-1H-pyrazolo[3,4-b]quinoline-6-carbonitrile (C18H9F3N4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-Phenyl-3-(trifluoromethyl)-1H-pyrazolo[3,4-b]quinoline-6-carbonitrile (CAS 1245716-38-4), molecular formula C18H9F3N4 and molecular weight 338.29 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Phenyl-3-(trifluoromethyl)-1H-pyrazolo[3,4-b]quinoline-6-carbonitrile 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.
