R-Alpha-Lipoic Acid Sodium Salt is the sodium salt form of the naturally occurring R-enantiomer of alpha-lipoic acid, a vitamin-like organosulfur compound. It has the molecular formula C₈H₁₃NaO₂S₂ and a molecular weight of 228.31 g/mol. The sodium salt form offers improved water solubility compared to the free acid, making it suitable for aqueous formulations.
Supplied as a food-grade material, it is used as a nutraceutical ingredient in supplement and functional food manufacturing. As the biologically active enantiomer, R-ALA sodium salt is the preferred form for applications requiring enhanced bioavailability and formulation stability in water-based systems.
SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers R-Alpha-Lipoic Acid Sodium Salt (CAS 176110-81-9) to customers in more than 40 countries.
