Chemical Structure
Description
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.
3-(Dimethylamino)-4-phenyl-N-(3-(trifluoromethyl)phenyl)-1H-pyrazole-1-carbothioamide (CAS 321553-14-4) is a high-purity analytical reference standard with the molecular formula C19H17F3N4S and a molecular weight of 390.43 g/mol.
The molecular framework of 3-(Dimethylamino)-4-phenyl-N-(3-(trifluoromethyl)phenyl)-1H-pyrazole-1-carbothioamide (C19H17F3N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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).
As a certified reference material (CRM), 3-(Dimethylamino)-4-phenyl-N-(3-(trifluoromethyl)phenyl)-1H-pyrazole-1-carbothioamide 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.
