Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 241.21 g/mol gives 5-Methyl-4-(4-(trifluoromethyl)phenyl)-1,2-dihydro-3h-pyrazol-3-imine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Methyl-4-(4-(trifluoromethyl)phenyl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 1221133-66-9), a certified reference material (molecular formula C11H10F3N3, MW 241.21 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-4-(4-(trifluoromethyl)phenyl)-1,2-dihydro-3h-pyrazol-3-imine (C11H10F3N3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 5-Methyl-4-(4-(trifluoromethyl)phenyl)-1,2-dihydro-3h-pyrazol-3-imine 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.
