Chemical Structure
Description
The occurrence of 2-(2H-1,2,3-Triazol-2-yl)ethanamine hydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(2H-1,2,3-Triazol-2-yl)ethanamine hydrochloride (CAS 4320-99-4), a certified reference material (molecular formula C4H8N4HCl, MW 148.59 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 2-(2H-1,2,3-Triazol-2-yl)ethanamine hydrochloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2-(2H-1,2,3-Triazol-2-yl)ethanamine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
