Chemical Structure
Description
3-Fluoro-4-(3-methyl-1h-pyrazol-1-yl)benzonitrile (CAS 1247592-75-1), molecular formula C11H8FN3 and molecular weight 201.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Fluoro-4-(3-methyl-1h-pyrazol-1-yl)benzonitrile (C11H8FN3) 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-Fluoro-4-(3-methyl-1h-pyrazol-1-yl)benzonitrile 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.
