Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating targeted therapies. It is also employed in the production of agrochemicals, where it contributes to the efficacy of certain herbicides and pesticides. Due to its reactive chlorine sites, it readily undergoes substitution reactions, enabling the introduction of various functional groups in drug design and optimization processes.
