4-Chloro-2-(2-tolyl)pyrimidine-5-boronic acid is primarily used as a key intermediate in the synthesis of various pharmaceutical compounds. Its boronic acid group makes it a valuable reagent in Suzuki-Miyaura cross-coupling reactions, which are widely employed to form carbon-carbon bonds in the development of complex organic molecules. This chemical is particularly useful in the production of biologically active pyrimidine derivatives, which are often explored for their potential therapeutic applications, including as kinase inhibitors in cancer treatment. Additionally, it serves as a building block in the creation of agrochemicals and materials science research, where its structural properties contribute to the design of novel compounds with specific functionalities.
