Compared with other compounds in its class, the molecular weight of 185.19 g/mol gives 2-(5-(Pyridin-3-yl)-1H-1,2,4-triazol-3-yl)acetonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(5-(Pyridin-3-yl)-1H-1,2,4-triazol-3-yl)acetonitrile (CAS 59282-72-3), a certified reference material (molecular formula C9H7N5, MW 185.19 g/mol) for analytical method development and quality control.
The molecular framework of 2-(5-(Pyridin-3-yl)-1H-1,2,4-triazol-3-yl)acetonitrile (C9H7N5) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
