Preliminary evaluation of some quaternary ammonium salts as phytoxic agents was written by Schlesinger, Arthur H.;Mowry, David T.. And the article was included in Journal of Agricultural and Food Chemistry in 1959.Safety of 1-(Cyanomethyl)pyridin-1-ium chloride This article mentions the following:
Some 60 quaternary ammonium salts RR1R2R3NX were prepared by standard chem. methods. Many of these salts exhibited considerable phytotoxicity in seed-germination tests. In a series of 1-substituted pyridinium bromides, maximum phytotoxicity was noticed when R was C12 to C14. Other active types of similar compounds are also mentioned. Lack of selectivity towards mono- or dicotyledeuous species is evident from these examples. In the experiment, the researchers used many compounds, for example, 1-(Cyanomethyl)pyridin-1-ium chloride (cas: 17281-59-3Safety of 1-(Cyanomethyl)pyridin-1-ium chloride).
1-(Cyanomethyl)pyridin-1-ium chloride (cas: 17281-59-3) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Safety of 1-(Cyanomethyl)pyridin-1-ium chloride
