Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its reactive acyl chloride group allows for easy attachment to amines or alcohols, enabling the formation of amide or ester linkages. Commonly employed in the preparation of heterocyclic compounds with potential neurological or cardiovascular activity. Also utilized in agrochemical research for designing novel active ingredients due to its stable dioxane ring structure that can enhance metabolic stability.
