Succinic acid is widely used in the food and beverage industry as an acidity regulator and flavor enhancer. It adds a sour or slightly tart taste to products such as soft drinks, desserts, and seasonings. In pharmaceuticals, it serves as an excipient and intermediate in the formulation of active ingredients, including in the production of sedatives, hypnotics, and barbiturates. It is also used in the manufacture of biodegradable polymers, such as polybutylene succinate (PBS), which are applied in eco-friendly plastics and packaging materials. In agriculture, succinic acid functions as a component in plant growth stimulants and soil conditioners. Additionally, it plays a role in the synthesis of dyes, perfumes, and resins in the chemical industry. Its ability to act as a building block in green chemistry makes it valuable for sustainable industrial processes.
