Used in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for treating various medical conditions. It serves as a key intermediate in the production of compounds with potential anti-inflammatory, antiviral, or anticancer properties. Additionally, it finds application in agrochemical research for creating pesticides or herbicides. Its role in organic synthesis is crucial for constructing complex molecules due to its reactive amine and chloro groups, which facilitate diverse chemical transformations.
