Production craft

Pyridine is coupled by treatment with sodium in ammonia followed by oxidation. The resulting 4,4′-bipyridine is then methylated with chloromethane to give the title compound.

Introduction
Although first synthesized in 1882, paraquat's herbicidal properties were not recognized until 1955. Paraquat was first manufactured and sold by ICI in early 1962, and is today among the most commonly used herbicides.
Paraquat is classified as a non-selective contact herbicide. The key characteristics that distinguish it from other agents used in plant protection products are:
  • It kills a wide range of annual grasses and broad-leaved weeds and the tips of established perennial weeds.
  • It is very fast-acting.
  • It is rain-fast within minutes of application.
  • It is partially inactivated upon contact with soil.
