Used as a key intermediate in the synthesis of thiazole-based pharmaceuticals, particularly in the production of certain antihypertensive and anti-inflammatory drugs. It serves as a building block in the development of active pharmaceutical ingredients (APIs) due to its reactive amino and chloro functional groups, which allow for further chemical modifications. Commonly employed in research and industrial settings for creating novel compounds with potential biological activity. Also utilized in agrochemical synthesis for developing crop protection agents. Its hydrochloride form enhances stability and solubility, making it suitable for use in various reaction conditions.
