Used as a key intermediate in organic synthesis, particularly in the preparation of complex molecules through umpolung (polarity reversal) strategies. Its structure allows for selective carbon-carbon bond formation, making it valuable in pharmaceutical synthesis where precise molecular architecture is required. The compound is also employed in the development of agrochemicals and functional materials due to its stability and reactivity as a masked acyl anion equivalent. Its derivatives can serve as building blocks in multistep syntheses, enabling efficient routes to ketones, aldehydes, and other carbonyl-containing compounds.
