Disodium succinate

Disodium succinate (CAS 150-90-3), also known by FEMA 3277, is the sodium salt of succinic acid used across food, pharmaceutical, and personal care manufacturing. It functions primarily as a pH buffer and flavor enhancer. This versatile ingredient stabilizes formulations and contributes a mild, characteristic taste profile to finished products. In food and beverage production, it acts as a flavor potentiator and acidulant, particularly in savory seasonings and soups.

It is frequently utilized in processed foods where it enhances umami character. Pharmaceutical manufacturers use it as a buffering agent in oral and injectable formulations, helping maintain target pH ranges throughout shelf life. In personal care, it supports pH regulation in rinse-off and leave-on products including shampoos, conditioners, and skin creams. It also appears as an intermediate in the synthesis of specialty chemicals and polymers.

The compound is essential for the production of biodegradable polymers and active pharmaceutical ingredients. Disodium succinate is supplied as a white crystalline powder in both anhydrous and hexahydrate forms. Buyers should confirm which hydration state is required before sourcing, as they differ in active content. Food-grade material conforming to FCC specifications is the most commonly traded grade for industrial use.

Pharmaceutical-grade material meeting USP or Ph.Eur. standards is available for regulated applications. These high-purity grades ensure compliance with international safety and quality protocols for medicine.
