4-Bromo-2,3-dichlorobenzoic acid is primarily used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its structure allows it to be a building block for more complex molecules, often contributing to the development of active ingredients in drugs or pesticides. The presence of halogen atoms in its structure makes it a valuable component in cross-coupling reactions, which are essential for creating carbon-carbon bonds in medicinal chemistry. Additionally, it may be utilized in research settings for studying chemical reactivity and designing novel compounds with specific biological activities.
