Application

Ethephon (2-Chloroethylphosphonic acid), a widely used plant growth regulator that induces scenescence and fruiting may be used to study its properties as a plant growth regulator, phosphorylating agent and as a butyrylcholinesterase inhibitor. Ethephon may be used as a reference compound in procedures designed to detect ethephon in biological materials.

Ethephon [(2-chloroethyl)phosphonic acid] has two seemingly unrelated types of biological activity. It is a major agrochemical absorbed by crops, slowly releasing ethylene as a plant growth regulator. Ethephon also inhibits the activity of plasma butyrylcholinesterase (BuChE) in humans, dogs, rats
