2,4-Dichlorophenoxy Acetic Acid (CAS 94-75-7)

2,4-Dichlorophenoxy acetic acid (2,4-D) is a synthetic auxin, belonging to a class of plant growth regulators. It is used as a supplement in plant cell culture media and serves as an active ingredient in herbicides. Its primary function is to control root elongation and cell production by disrupting the actin cytoskeleton. As an herbicide, 2,4-Dichlorophenoxy Acetic Acid is colorless, odorless, and widely utilized for managing broad-leaved weeds, woody plants, and aquatic weeds. It exhibits degradation capabilities through microorganisms present in soil and water. Being a synthetic auxin, 2,4-Dichlorophenoxy Acetic Acid is predominantly utilized globally in various herbicide products, with nine different forms available, often in powder or liquid form. Physically, 2,4-dichlorophenoxyacetic acid is an odorless white to tan solid that sinks in water. It falls under the class of organic compounds known as chlorophenoxyacetates, characterized by a phenoxyacetate structure with chlorine atoms on the benzene ring. The compound is practically insoluble in water and is considered relatively neutral. Its detection is primarily observed in urine samples, and it tends to localize within the cell membrane as predicted by its logP value. 2,4-Dichlorophenoxyacetic acid holds a formal rating as a possible carcinogen (IARC 2B) and is identified as a potentially toxic compound.
