Potassium 2,4,5-trichlorophenoxyacetate, often abbreviated as K-2,4,5-T or simply 2,4,5-T, is a chemical compound that belongs to the class of chlorophenoxy herbicides. It is derived from phenoxyacetic acid and is specifically characterized by the presence of three chlorine atoms attached to the aromatic ring. 2,4,5-T has been widely used as a selective herbicide to control the growth of broadleaf weeds in various agricultural and forestry applications. It acts by disrupting the plant′s hormonal balance, particularly the growth regulator auxin, leading to uncontrolled growth and eventual death of the targeted plants.
