Used primarily in pharmaceutical research and development, this compound serves as a key intermediate in the synthesis of various biologically active molecules. Its structure is particularly valuable in the creation of quinazoline derivatives, which are explored for their potential as kinase inhibitors. These inhibitors are crucial in targeted cancer therapies, as they can interfere with specific signaling pathways that promote tumor growth. Additionally, it is employed in the study of enzyme interactions and the development of novel therapeutic agents for diseases involving abnormal cell proliferation. Its nitro and chloro groups make it a versatile building block for further chemical modifications in drug discovery processes.
