Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of heterocyclic compounds like pyrimidines and fused ring systems that exhibit biological activity. It serves in the development of antiviral, anticancer, and anti-inflammatory agents due to its ability to introduce functionalized malonate structures into complex molecules. Also applied in agrochemicals for constructing active ingredients in pesticides and herbicides. Its reactivity allows for efficient construction of nitrogen-containing scaffolds in medicinal chemistry research.
