Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of thiazole-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in organic synthesis for creating complex heterocyclic compounds. Its aldehyde functional group allows for easy modification, enabling the formation of Schiff bases, imines, and other derivatives important in medicinal chemistry. Also employed in the preparation of agrochemicals and bioactive molecules due to its reactivity and structural features.
