Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical industry for constructing complex molecules. Its functional groups allow for cross-coupling reactions, making it valuable in the development of active pharmaceutical ingredients. The aryl chloro substituent enables substitutions under palladium-catalyzed conditions, while the alkyl bromo group supports nucleophilic displacements, facilitating the formation of carbon-carbon and carbon-heteroatom bonds. It is also employed in agrochemical synthesis for building herbicidal and insecticidal compounds due to its stability and reactivity profile.
