Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in creating active ingredients in drug discovery. Commonly employed in cross-coupling reactions such as Suzuki and Negishi couplings to build complex molecules. Also utilized in agrochemicals for the production of herbicides and fungicides due to its stability and reactivity. Preferred in research settings for labeling and probing biological systems when modified with detectable tags.
