Chemical Structure
Description
The molecular framework of 4-Iodo-1-methyl-1H-1,2,3-triazole (C3H4IN3) is characterized by a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 4-Iodo-1-methyl-1H-1,2,3-triazole (CAS 856861-41-1), a certified reference material (molecular formula C3H4IN3, MW 208.99 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.
