Description
Sodium succinate (CAS 150-90-3) is the disodium salt of succinic acid, commercially known under names including Disodium Succinate, SS 50, Soduxin, and FEMA 3277. It carries no E-number designation in the EU but is recognised under FEMA 3277 for flavouring applications. Its molecular formula is C4H6O4.2Na.
In food and beverage formulations, sodium succinate functions as a pH buffer and flavour-modifying additive, contributing a mild umami-adjacent taste profile at low concentrations. In pharmaceutical manufacturing, it serves as a buffering agent in parenteral formulations and as a catalyst in specific esterification reactions, where its ionic character stabilises reaction conditions.
Sodium succinate is available in food-grade and pharmaceutical-grade crystalline powder forms, with compliance to FCC and Ph.Eur. standards depending on grade. The substance falls under REACH regulation (EC 205-778-7) and is classified under HS code 29171990. Packaging formats typically include 25 kg bags or fibre drums.
