Chemical Structure
Description
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.
CATO supplies 1h-1,2,4-triazole-1-ethanamine, hydrobromide (1:1) 845874-51-3 (CAS 845874-51-3), a certified reference material (molecular formula C4H8N4HBr, MW 193.05 g/mol) for analytical method development and quality control.
1h-1,2,4-triazole-1-ethanamine, hydrobromide (1:1) 845874-51-3 (C4H8N4HBr) contains a nitrile group, bromine 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.
