Used as a strong acidic catalyst in organic synthesis, particularly in esterification and hydrolysis reactions. Effective in promoting condensation reactions due to its high acidity and stability. Commonly applied in the production of fine chemicals, pharmaceuticals, and agrochemicals where a water-soluble, non-oxidizing acid is required. Also utilized in electroplating baths to maintain acidic conditions and improve conductivity. Its solution form allows for easy handling and dosing in industrial processes.
