Chemical Structure
Description
The molecular framework of 1-(2,2-Difluoroethyl)-1h-pyrazole-3-carbaldehyde (C6H6F2N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(2,2-Difluoroethyl)-1h-pyrazole-3-carbaldehyde (CAS 1310379-50-0), molecular formula C6H6F2N2O and molecular weight 160.12 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.
