2,2-Dimethylpropanoyl chloride (also known as pivaloyl chloride) is an acid chloride with the molecular formula C₅H₉ClO. It is a reactive organic compound widely used as an acylating agent in organic synthesis. It is commonly employed to introduce the pivaloyl (tert-butylcarbonyl) group into molecules during the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. Due to its high reactivity toward nucleophiles, it is mainly used as a synthetic intermediate in laboratory and industrial chemical processes.
