Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.99 g/mol gives 3-Iodo-1-methyl-1h-1,2,4-triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Iodo-1-methyl-1h-1,2,4-triazole (CAS 55847-41-1) is a high-purity analytical reference standard with the molecular formula C3H4IN3 and a molecular weight of 208.99 g/mol.
The molecular framework of 3-Iodo-1-methyl-1h-1,2,4-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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
