Used as an intermediate in organic synthesis, particularly in pharmaceutical manufacturing. It serves as a stabilizing agent or counterion in the formulation of certain antiviral and antiparasitic drugs. Its salt form improves solubility and bioavailability of active ingredients. Also employed in research settings for crystallization studies due to its ability to form stable complexes with organic cations. Commonly found in lab-scale preparations requiring mild, water-soluble acidic components with buffering capacity.
