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 biologically active molecules. Commonly employed in medicinal chemistry research for building isoindoline-based scaffolds that exhibit antitumor and anti-inflammatory properties. Also utilized in the preparation of fluorescent probes and labeled compounds for biochemical assays due to its favorable reactivity and stability.
