3-(2-aminoethyl)-4,5-dihydro-1H-1,2,4-triazol-5-one hydrochloride CAS 879635-07-1

Description

The occurrence of 3-(2-aminoethyl)-4,5-dihydro-1H-1,2,4-triazol-5-one hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(2-aminoethyl)-4,5-dihydro-1H-1,2,4-triazol-5-one hydrochloride (CAS 879635-07-1) is a high-purity analytical reference standard with the molecular formula C4H8N4OHCl and a molecular weight of 164.59 g/mol.

3-(2-aminoethyl)-4,5-dihydro-1H-1,2,4-triazol-5-one hydrochloride (C4H8N4OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
