Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive compounds with antimicrobial, antifungal, and anti-inflammatory properties. It serves as a building block in heterocyclic chemistry due to its stable thiazole ring, which is common in many drug molecules. Also employed in the preparation of dyes, optical brighteners, and fluorescent whiteners for textiles and paper. Its derivatives are investigated for use in organic electronics and as ligands in catalytic reactions.
