2-(3-Chloro-1H-1,2,4-triazol-1-yl)acetonitrile (CAS 1322604-41-0) is a high-purity analytical reference standard with the molecular formula C4H3ClN4 and a molecular weight of 142.55 g/mol.
2-(3-Chloro-1H-1,2,4-triazol-1-yl)acetonitrile (C4H3ClN4) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
