Chemical Structure
Description
The molecular framework of 1-[5-(butan-2-yl)-1H-1,2,4-triazol-3-yl]ethan-1-amine hydrochloride (C8H16N4HCl) is characterized by a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-[5-(butan-2-yl)-1H-1,2,4-triazol-3-yl]ethan-1-amine hydrochloride (CAS 1787904-43-1), molecular formula C8H16N4HCl and molecular weight 204.70 g/mol, is a CATO reference standard with documented purity and traceability.
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.
