Chemical Structure
Description
The molecular framework of 5-(3-Fluorophenyl)-4-iodo-1H-pyrazol-3-amine (C9H7FIN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
CATO supplies 5-(3-Fluorophenyl)-4-iodo-1H-pyrazol-3-amine (CAS 1355172-38-1), a certified reference material (molecular formula C9H7FIN3, MW 303.07 g/mol) for analytical method development and quality control.
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.
