Chemical Structure
Description
The molecular framework of 3,5-Dimethyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenol (C12H11F3N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).
3,5-Dimethyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenol (CAS 1393125-42-2), molecular formula C12H11F3N2O and molecular weight 256.22 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.
As a certified reference material (CRM), 3,5-Dimethyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenol 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.
