Chemical Structure
Description
3-(Chloromethyl)-1h-1,2,4-triazole hydrochloride (CAS 95728-51-1), molecular formula C3H4ClN3HCl and molecular weight 153.99 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C3H4ClN3HCl, 3-(Chloromethyl)-1h-1,2,4-triazole hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 153.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
