1. Food industry: Propionic acid can be used as a food preservative, often used for the preservation of bread, dough, candy, feed, etc., to extend the shelf life of food.

2. Feed additives: PA can also be used as a preservative and acid regulator in animal feed. It can prevent the growth of microorganisms in the feed, maintain the freshness of the feed, and also help animals digest and absorb the feed.

3. Chemical synthesis: chemical propionic acid can be used as a raw material or reagent for organic synthesis. It can react with other compounds to form different compounds. For example, propionic acid can be synthesized into propionate by esterification, and acrylic acid can also be formed by dehydration.

4. Pharmaceutical industry: Propionic acid has some applications in the pharmaceutical industry. For example, it can be used as a raw material for certain drugs, for the synthesis of drug intermediates or other compounds; It can also be used as an ingredient in local anesthetic drugs.

5. Other fields: Propionic acid can also be used in coatings, plastics, solvents and other fields. It can be used as an acidic substance to regulate pH, and participate in chemical reactions or play some functional role.
