Chemical Structure

3-iodo-5-methyl-4H-1,2,4-triazole CAS 23579-76-2 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 3-iodo-5-methyl-4H-1,2,4-triazole.

3-iodo-5-methyl-4H-1,2,4-triazole (CAS 23579-76-2), molecular formula C3H8IN3 and molecular weight 213.02 g/mol, is a CATO reference standard with documented purity and traceability.

3-iodo-5-methyl-4H-1,2,4-triazole (C3H8IN3) contains iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
