Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antidiabetic drugs. It serves as a building block for pioglitazone and related thiazolidinedione derivatives, which act as insulin sensitizers in type 2 diabetes treatment. Its structure allows for efficient modification and coupling reactions in medicinal chemistry, enhancing drug stability and bioavailability. Also explored in agrochemical research for designing novel pesticides due to its nitrogen-rich heterocyclic core.
