Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. Its structure enables selective binding to enzyme active sites, making it valuable in developing drugs that modulate cell signaling pathways. Commonly employed in the preparation of antitumor agents due to its ability to mimic purine bases in nucleotide-binding pockets. Also utilized in the design of fluorescent probes for biochemical assays, leveraging its nitro and chloro functionalities for further derivatization.
