5-Fluoroquinazoline is widely used in pharmaceutical research and development, particularly as a key intermediate in the synthesis of various biologically active compounds. Its quinazoline core structure makes it valuable in the design of anticancer agents, as it can inhibit enzymes like tyrosine kinases that are involved in cancer cell proliferation. Additionally, it serves as a building block for creating compounds with potential antiviral and antibacterial properties, contributing to the discovery of new therapeutic agents. Its applications also extend to agrochemical research, where it is explored for developing novel pesticides and herbicides.
