Paraquat Dichloride is a poisonous dipyridilium compound which has been researched for use as a contact herbicide. Paraquat Dichloride belongs to the viologen family, which comprises redox-active heterocycles sharing a similar structure. Paraquat Dichloride exhibits rapid and non-selective action, effectively eradicating green plant tissue upon contact. Its redox activity, generating superoxide anions, renders it toxic to both humans and animals.
