Disodium succinate, also known as sodium succinate, white crystalline particle, odorless, not deliquescent in the air; soluble in water, and insoluble in organic solvents. Aqueous solution has a shellfish fresh flavor and no acidic taste. It can be used as a food flavoring agent, acidifier, or buffering agent.??
Succinic acid disodium salt is used to prepare buffer solution for the quantitative analysis of auxins.It can be also used:
To study the effect of liquid phase on the basic properties of α-tricalcuim phosphate (α-TCP) based cement, BIOPEX.
In the synthesis of cadmium sulfide (CdS) nanoparticles using thiourea as a source for sulfide.
??
ChEBI: Sodium succinate (anhydrous) is a sodium salt that is the disodium salt of succinic acid. The hexahydrate form is used as an ingredient of topical preparations for the treatment of cataract. It contains a succinate(2-).?? ??
Disodium succinate is produced by neutralizing succinic acid with sodium hydroxide. The anhydrous material is then dried at 120°C in hot air and pulverized to obtain.?? ??
Disodium succinate is used in the food industry as an acidity regulator and flavor enhancer.Purification Methods
Crystallise it twice from water (1.2mL/g) and dry it at 125o. It has been freed from other metal ions by passage of a 0.1M solution through a column of Dowex resin A-1 (Na form). It is hygroscopic. [Beilstein 2 H 606, 2 IV 1908.]??????? ?? ?? ? ???
