4-(2-Chloro-6-fluorophenyl)-1-methyl-1h-pyrazol-5-amine CAS 1248079-27-7 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 4-(2-Chloro-6-fluorophenyl)-1-methyl-1h-pyrazol-5-amine.

CATO supplies 4-(2-Chloro-6-fluorophenyl)-1-methyl-1h-pyrazol-5-amine (CAS 1248079-27-7), a certified reference material (molecular formula C10H9ClFN3, MW 225.65 g/mol) for analytical method development and quality control.

The molecular framework of 4-(2-Chloro-6-fluorophenyl)-1-methyl-1h-pyrazol-5-amine (C10H9ClFN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine 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), 4-(2-Chloro-6-fluorophenyl)-1-methyl-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.
