Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of thiazole-based drugs which exhibit antimicrobial, antifungal, and anti-inflammatory activities. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) where the thiazole ring enhances metabolic stability and bioavailability. Also utilized in agrochemicals for developing fungicides and plant growth regulators due to its ability to interfere with microbial and fungal metabolic pathways. Its hydrochloride salt form improves solubility and handling in aqueous reaction systems.
