Widely used as an intermediate in the production of herbicides, particularly 2,4-D (2,4-dichlorophenoxyacetic acid), a common broadleaf weed killer in agriculture and lawn care. It also serves in the synthesis of other chlorinated compounds used in wood preservatives, disinfectants, and dye manufacturing. Due to its antimicrobial properties, it has been used in some industrial antifouling and antiseptic applications. Additionally, it finds use in the production of certain pharmaceuticals and pesticides. However, its use is regulated in many areas due to environmental persistence and toxicity concerns.
