Propionic Acid Pharmaceutical
In the pharmaceutical field, propionic acid can be used to produce alanine, which is further used in vitamin synthesis. China is a major producer of vitamins, and the alanine required for production is synthesized from propionic acid. China annually imports propionic acid for this purpose. Powders containing calcium propionate and ointments or solutions with certain concentrations can treat diseases caused by parasitic fungi on the skin and can also serve as pharmaceutical intermediates.
