Chemical Structure

2-(chloromethyl)-2H-1,2,3-triazole CAS 80199-90-2 chemical structure

Description

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.

2-(chloromethyl)-2H-1,2,3-triazole (CAS 80199-90-2) is a high-purity analytical reference standard with the molecular formula C3H4ClN3 and a molecular weight of 117.54 g/mol.

Based on its molecular formula C3H4ClN3, 2-(chloromethyl)-2H-1,2,3-triazole contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 117.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
