Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting tyrosine kinases involved in cancer cell proliferation. It serves as a building block in the development of small-molecule drugs due to its ability to bind selectively to ATP pockets in enzyme targets. Also explored in the design of anti-inflammatory and neuroprotective agents owing to its structural similarity to bioactive indole derivatives. Its derivatization enhances metabolic stability and blood-brain barrier penetration in drug candidates.
