  • Applications

    L-Arginine, (2S)-2-hydroxybutanedioate (1:1) (CAS number: 93964-77-3) is the malate salt of L-arginine. It is used as a source of the amino acid in pharmaceuticals and nutrition formulations, including oral supplements and parenteral nutrition. It is commonly present in sports nutrition and functional foods as an arginine replenishing ingredient. In cosmetics and personal care, arginine malate can function as a conditioning agent and help balance formulation pH. It is also used in animal nutrition and feed formulations as an arginine supplement. Additionally, as an amino acid salt, it can serve as a chemical intermediate for the synthesis of arginine-derived compounds in industrial manufacturing.
