Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to the presence of both chloro and ester functional groups that allow for further chemical modifications. The tert-butyl ester group provides stability during synthetic transformations and can be selectively deprotected under mild acidic conditions. Its picolinoyl core is valuable in constructing bioactive molecules, especially in the development of crop protection agents with improved selectivity and efficacy. Commonly employed in multi-step organic syntheses where controlled reactivity and compatibility with other functional groups are required.
