  • Applications

    Ephedrine hydrochloride is used in pharmaceuticals as a sympathomimetic active ingredient in certain decongestant and stimulant formulations. It also serves as a precursor and building block for organic synthesis, including the production of other alkaloids and various drug intermediates. In industrial contexts, it is used as a precursor and intermediate for chemical synthesis and as a reference material for research and development. Additionally, it may be used as a reagent and reference material for analytical method development, subject to local regulations.
