Used as a key intermediate in the synthesis of pyrazoloquinazoline derivatives, which exhibit significant biological activities such as antitumor, antiviral, and anti-inflammatory properties. It serves in pharmaceutical research for developing kinase inhibitors and other targeted therapies. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building heterocyclic compounds with potential therapeutic effects. Also employed in the design of novel fluorescent probes due to its ability to form conjugated systems useful in imaging and sensor applications.
