Chemical Structure
Description
1,3-Bis(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde (C16H10F2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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.
1,3-Bis(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde (CAS 618098-59-2) is a high-purity analytical reference standard with the molecular formula C16H10F2N2O and a molecular weight of 284.26 g/mol.
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), 1,3-Bis(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde 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.
