Organophosphorus pesticide chemical composition

Organophosphorus pesticides are mostly ester (or amide) compounds, and the hydrocarbon groups in the molecular structure of traditional organophosphorus pesticides are mostly aliphatic hydrocarbon groups and substituted benzene aromatic hydrocarbon groups. Since heterocyclic compounds tend to have high biological activity, some phosphate compounds have been synthesized by introducing heterocyclic structures into organophosphorus pesticide molecules.
