  • Applications

    Sodium L-aspartate (CAS 18962-61-3) is commonly used as a nutrient source of aspartate in cell culture media and fermentation processes, supplying an amino‑acid supplement for microbial and mammalian production systems. It can act as a buffering and stabilizing additive in biochemical and pharmaceutical formulations to help maintain pH and formulation integrity. It may serve as a precursor or intermediate in the synthesis of other aspartate derivatives and in the production of poly(aspartate)-based biodegradable polymers. In cleaning formulations, it can function as a chelating/sequestering agent that binds metal ions, and in cosmetics and personal care it can serve as a conditioning or humectant-type salt and a pH adjuster.
