  • Applications

    Asparagine (CAS 70-47-3) is a non-essential amino acid used as a nutritional component and a building block in biotechnology and pharmaceutical manufacturing; it serves in cell culture media formulations that support protein production in bioprocessing and recombinant protein workflows. It is also used in specialized nutrition formulations and parenteral nutrition regimens where amino acid supplementation is required. In the food sector, asparagine appears in fortified amino acid blends and is examined in processing research to optimize formulation and sensory properties. In research and analytical chemistry, it serves as a reference standard for amino acid quantification and protein characterization by HPLC/LC-MS. In materials and biotech, asparagine can act as a feedstock or starting monomer for polypeptide-based polymers and related biomaterials.
