Chemical Structure
Description
5-Fluoro-1-(p-tolyl)-1H-pyrazole-4-carbonitrile (CAS 1269293-01-7), molecular formula C11H8FN3 and molecular weight 201.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Fluoro-1-(p-tolyl)-1H-pyrazole-4-carbonitrile (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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-Fluoro-1-(p-tolyl)-1H-pyrazole-4-carbonitrile 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.
