Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure, featuring a chlorine at the 4-position, fluorine at the 6-position, and a trifluoromethyl group at the 2-position on the quinazoline core, enables selective binding to enzyme active sites, enhances drug efficacy by improving cell membrane permeability and molecular stability. Commonly employed in research settings to design compounds with antitumor and anti-inflammatory activities. Also utilized in agrochemicals for creating novel pesticides due to its stability and reactivity profile.
