Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 112.13 g/mol gives 2-(1H-1,2,3-Triazol-5-yl)ethanamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(1H-1,2,3-Triazol-5-yl)ethanamine (CAS 52845-67-7), molecular formula C4H8N4 and molecular weight 112.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(1H-1,2,3-Triazol-5-yl)ethanamine (C4H8N4) is characterized by a nitrile group. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
