Paraquat

Paraquat,Etiam Paraquat dichloride, Methyl viologen dichloride, Crisquat, Dexuron, Esgram, Gramuron, Ortho Paraquat CL, Para-col, Pillarxone, Tota-col, Toxer Total, PP148, Cyclone, Gramixel, Gramoxone, Pathclear, et AH 501 in commercio appellatum. nomine triviali, vel rite N,N′-dimethyl-4,4′-bipyridinium dichloridum, nomine systematico, est compositum organicum cuius formula chemica est [(C6H7N)2]Cl2. Solidum flavum,"Paraquat (Paraquat dichloride)," in NIOSH Pocket Guide to Chemical Hazards (Centers for Disease Control and Prevention). viologenum describitur, familiae heterocyclorum redox-activorum structuram similem habentium. Hic sal est unus ex herbicidis latissimis adhibitis. Cito et generatim agit, texturam plantarum contactu torrens, hominibus et animalibus quoque toxicum. Coniungitur ad progressum morbi Parkinsoniani..Kamel 2013. Nomen a locis para in exemplaribus substitutionibus arene cationtis ammonii quaternarii nitrogenii derivatur. Quantitates aliquando dicuntur per massam cationtum solum (cation paraquat, ion paraquat); alii sales, cum aliis aniontibus praeter chloridum, fiunt. Eius actio redox, quae anionta superoxidi giginit, revera est toxicitatis causa.
