Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and plant growth regulators. Its structure allows for selective reactivity in coupling reactions, making it valuable in building complex organic molecules. Commonly employed in the preparation of pyrimidine-based active ingredients where the tert-butyl group enhances lipophilicity and the chloro substituent enables further functionalization. Also utilized in research for designing novel compounds with biological activity.
