CAS 72-17-3: Sodium lactate

Sodium dl-lactate is a sodium salt of lactic acid. It is used as an antimicrobial agent, and has been shown to have significant cytotoxicity against tumor cells. Sodium dl-lactate is also used in clinical practice for the treatment of metabolic acidosis, and to increase the blood lactate concentration during labor. In addition, this compound has been found to have important physiological effects on energy metabolism and cell volume regulation. The disulfide bond between two molecules of dl-lactate can be cleaved by thiol oxidoreductases or reduced by glutathione reductase to form 2 molecules of pyruvic acid and 2 molecules of hydrogen peroxide. This reaction provides a means for lactate oxidation that may be important in wastewater treatment and in the production of biogas from organic wastes.

Useful chiral synthon; building block for depsipeptides.Sodium DL-lactate, 60% w/w aq. Soln is used as a food additive, plasticizer for casein, preservative, acidity regulator, bulking agent, and in shampoo and liquid soaps. It is also used for the treatment for arrhythmias and sympathomimetics. It is useful chiral synthon and building block for depsipeptides. It is used as a corrosion inhibitor in alcohol antifreeze mixtures, flavoring agent, emulsifier, corrosion inhibitor and pH control agent.This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

Lactic acid is a natural product that has been used for many years as an antimicrobial agent in wastewater treatment. It is also used in the food industry to prevent the growth of bacteria and fungi, and as a preservative. Lactic acid has been shown to have a physiological effect on locomotor activity, which may be due to its ability to convert pyruvate into lactate. Lactic acid also inhibits the growth of some bacterial strains by increasing the disulfide bond formation between two cysteine residues. The sodium salt form of lactic acid is more soluble than the acid form and can be used as an experimental model for studying sodium-lactate interactions. Sodium lactate is used in maternal blood transfusions to increase blood pH levels during labor, and is also added to water vapor for humidification purposes.
