Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Chlorophenyl)-3-(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde.
1-(3-Chlorophenyl)-3-(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde (CAS 618098-66-1), molecular formula C16H10ClFN2O and molecular weight 300.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3-Chlorophenyl)-3-(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde (C16H10ClFN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(3-Chlorophenyl)-3-(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
