Chemical Structure

5-Methyl-1-(5-(trifluoromethyl)pyridin-2-yl)-1,2-dihydro-3h-pyrazol-3-imine CAS 1171925-31-7 chemical structure

Description

5-Methyl-1-(5-(trifluoromethyl)pyridin-2-yl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 1171925-31-7) is a high-purity analytical reference standard with the molecular formula C10H9F3N4 and a molecular weight of 242.20 g/mol.

The molecular framework of 5-Methyl-1-(5-(trifluoromethyl)pyridin-2-yl)-1,2-dihydro-3h-pyrazol-3-imine (C10H9F3N4) 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.

As a certified reference material (CRM), 5-Methyl-1-(5-(trifluoromethyl)pyridin-2-yl)-1,2-dihydro-3h-pyrazol-3-imine 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.
