1-Azaxanthone is primarily used in pharmaceutical research due to its structural similarity to bioactive xanthone derivatives. It serves as a key scaffold in the development of compounds with potential antitumor, antiviral, and antimicrobial properties. Its nitrogen-containing heterocyclic framework enhances binding affinity to certain biological targets, making it valuable in medicinal chemistry for designing enzyme inhibitors and receptor modulators. Additionally, 1-azaxanthone derivatives are explored for their antioxidant activity and potential use in treating neurodegenerative diseases. The compound also finds application in materials science, where its conjugated system contributes to the development of fluorescent probes and organic electronic materials.
