Used primarily as an intermediate in organic synthesis, this compound is valuable in the preparation of pharmaceuticals and agrochemicals. Its reactive acid chloride group allows it to readily form amide or ester bonds, making it useful in constructing complex molecules. It is often employed in the synthesis of active ingredients in crop protection products due to the presence of the chloro and methyl substituents that can influence biological activity. Additionally, it serves in the development of specialty polymers where controlled branching or functional side chains are required. Handling requires caution due to its moisture sensitivity and potential to release hydrogen chloride upon hydrolysis.
