Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds with potential anticonvulsant and anti-inflammatory properties. Its structural framework supports the design of novel heterocyclic drugs. Also employed in research settings for the preparation of isoindoline derivatives, which are explored for their activity in central nervous system disorders. Additionally, it serves as a building block in the creation of functional materials and specialty chemicals due to its stable ring system and functional group compatibility.
