5-Butyl-6-chloropyrazine-2,3-dicarbonitrile (CAS 72111-60-5) is a high-purity analytical reference standard with the molecular formula C10H9ClN4 and a molecular weight of 220.66 g/mol.
5-Butyl-6-chloropyrazine-2,3-dicarbonitrile (C10H9ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
