Reported in EPA TSCA Inventory.

The CAS registry number of Sodium tartrate is 868-18-8. Its EINECS registry number is 212-773-3. The systematic name is disodium (2R,3R)-2,3-dihydroxybutanedioate. In addition, the molecular formula is C₄H₄Na₂O₆ and the molecular weight is 194.05. Its crystal structure captures a very precise amount of water. And it is also a common primary standard for Karl Fischer titration. What's more, it should be stored in sealed container, and put in a cool and dry place.

Physical properties about this chemical are: (1)ACD/LogP: -1.43; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -5.86; (4)ACD/LogD (pH 7.4): -6.18; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 6; (10)#H bond donors: 4; (11)#Freely Rotating Bonds: 5; (12)Polar Surface Area: 93.06 Å²; (13)Flash Point: 209.4 °C; (14)Enthalpy of Vaporization: 75.13 kJ/mol; (15)Boiling Point: 399.3 °C at 760 mmHg; (16)Vapour Pressure: 4.93E-08 mmHg at 25°C.

Preparation and uses of Sodium tartrate: it can be prepared by L-tartaric acid. Heat the L-tartaric acid at first. And then after a series of neutralization by sodium hydroxide, condensation and crystallization you can get the desired product. In addition, it is used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings. And it also can be used as a food additive, slow granule, emulsion salt, antioxidants, antioxidant synergistic agent and chelating agent.
