Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-3-phenyl-4-(trifluoromethyl)-1H-pyrazole.
1-Methyl-3-phenyl-4-(trifluoromethyl)-1H-pyrazole (CAS 96256-48-3), molecular formula C11H9F3N2 and molecular weight 226.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Methyl-3-phenyl-4-(trifluoromethyl)-1H-pyrazole (C11H9F3N2) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Methyl-3-phenyl-4-(trifluoromethyl)-1H-pyrazole 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.
