Used primarily in the synthesis of pharmaceuticals, particularly as a key intermediate in the production of antihistamines, H2-receptor antagonists like famotidine. It plays a crucial role in developing drugs for allergic reactions, gastrointestinal disorders. Additionally, it is applied in organic synthesis for creating heterocyclic thiazole compounds, which are essential in medicinal chemistry. It also contributes to the preparation of dyes and pigments for coloration in various materials. In research, it is employed to study thiazole derivatives with potential for new therapeutic agents. Limited applications exist in agrochemicals for certain pesticides.
