Chemical Structure
Description
3-Phenyl-5-(trifluoromethyl)-1H-pyrazole (CAS 4027-54-7), molecular formula C10H7F3N2 and molecular weight 212.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Phenyl-5-(trifluoromethyl)-1H-pyrazole (C10H7F3N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-Phenyl-5-(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.
