Chemical Structure

3-(1-chloroethyl)-4-methyl-4H-1,2,4-triazole hydrochloride CAS 1803608-10-7 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.

3-(1-chloroethyl)-4-methyl-4H-1,2,4-triazole hydrochloride (CAS 1803608-10-7), molecular formula C5H8ClN3HCl and molecular weight 182.05 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(1-chloroethyl)-4-methyl-4H-1,2,4-triazole hydrochloride (C5H8ClN3HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 182.05 g/mol, it falls into the medium-molecular-weight range. 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.
