Description and Uses
4-CPA is a plant growth regulator. It is moderately soluble in water and is quite volatile. Little is known about its persistence in soil and aquatic systems. It is moderately toxic to mammals and has a high potential for bioaccumulation. It is also a recognised irritant. It is moderately toxic to birds, honeybees and most aquatic organisms. However, it has a relatively low toxicity to fish.
4-chlorophenoxy acetic acid (4-CPA), a chlorine derivative of phenoxyacetic acid (PA), is a plant growth regulator used as a herbicide.
