Chemical Structure
Description
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.
3-(5-(Pyridin-2-yl)-1H-1,2,4-triazol-3-yl)aniline (CAS 1092305-59-3), molecular formula C13H11N5 and molecular weight 237.26 g/mol, is a CATO reference standard with documented purity and traceability.
3-(5-(Pyridin-2-yl)-1H-1,2,4-triazol-3-yl)aniline (C13H11N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
