Description
L-Asparagine monohydrate (CAS 5794-13-8) is a naturally occurring amino acid supplied as its stable monohydrate form, also referenced as H-Asn-OH H2O or H-L-ASN-OH. It carries no E-code designation. It belongs to the amino acid building blocks used across formulation and biological research applications.
In personal care formulations, it functions as a humectant and skin conditioner by attracting and retaining moisture at the cellular level, and as a buffer to stabilise product pH. In pharmaceutical and biotech manufacturing, it serves as a nitrogen source in cell culture media and supports protein synthesis pathways in biological systems.
L-Asparagine monohydrate is available in reagent and technical grades, with select batches meeting Ph.Eur. or FCC specifications for pharmaceutical and food-grade applications. The substance is registered under REACH (EC 611-593-6) and is classified under HS code 29241900. Packaging formats typically range from laboratory quantities to bulk.
