Used as a key intermediate in the synthesis of fluorinated quinazoline derivatives, which show significant biological activity, particularly in anticancer and antimicrobial agents. Its structure allows for selective substitutions at the 4-position, enabling the development of targeted kinase inhibitors. Commonly employed in pharmaceutical research for designing drugs that modulate enzyme activity, especially in tyrosine kinase and EGFR inhibitor pathways. Also utilized in agrochemicals for developing herbicides and pesticides due to its stability and reactivity profile.
