Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and anticonvulsant drugs. Its structure supports the formation of heterocyclic scaffolds that are important in medicinal chemistry. It is also employed in research settings for the preparation of novel bioactive molecules and in the study of structure-activity relationships within benzothiadiazine derivatives. Its reactivity allows for selective substitutions, making it valuable in optimizing drug candidates during early-stage drug discovery.
