CAS 69833-18-7: 2,4-diamino-4-oxobutanoic acid hydrate

DL-Asparagine monohydrate is used as a pharmaceutical intermediate. It is used to prepare DL-asparaginium nitrate. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

This is an analytical chemical that is used to measure the concentration of asparagine in human serum and other biological fluids. Asparaginase is a metastable molecule, which means it has a fleeting lifetime. It can be detected by using the turbidimetric method or the ultracentrifugation method. The chromatographic separation of this compound can be done using an HPLC-MS/MS system with enantiomeric analysis. This technique separates molecules based on their chemical properties and the physical properties of their ions.

Applications Asparagine Monohydrate, is a naturally occurring amino acid that is not an essential for humans and can be synthesized from central metabolic pathway intermediates.
