1-(4-Fluorophenyl)-3-(p-tolyl)-1H-pyrazol-5-amine CAS 618098-12-7

Description

Compared with other compounds in its class, the molecular weight of 267.30 g/mol gives 1-(4-Fluorophenyl)-3-(p-tolyl)-1H-pyrazol-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(4-Fluorophenyl)-3-(p-tolyl)-1H-pyrazol-5-amine (CAS 618098-12-7), a certified reference material (molecular formula C16H14FN3, MW 267.30 g/mol) for analytical method development and quality control.

The molecular framework of 1-(4-Fluorophenyl)-3-(p-tolyl)-1H-pyrazol-5-amine (C16H14FN3) 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.

As a certified reference material (CRM), 1-(4-Fluorophenyl)-3-(p-tolyl)-1H-pyrazol-5-amine 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.
