Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. It serves as a building block in organic reactions where selective bromo and chloro substitutions are required for further functionalization. Its carboxylic acid group allows for coupling reactions, making it valuable in the preparation of more complex molecules in medicinal chemistry. Also employed in the production of dyes and specialty polymers where halogenated aromatic structures enhance stability and reactivity.
