Chemical Structure
Description
The molecular framework of 2-(1H-1,2,3-Triazol-4-yl)ethan-1-ol hydrochloride (C4H7N3OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-(1H-1,2,3-Triazol-4-yl)ethan-1-ol hydrochloride (CAS 2138388-61-9) is a high-purity analytical reference standard with the molecular formula C4H7N3OHCl and a molecular weight of 149.58 g/mol.
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.
