  • Applications

    Being the sodium salt of a (2S)-2-amino-5-hydroxy-5-oxopentanoate, sodium;(2S)-2-amino-5-hydroxy-5-oxopentanoate is commonly viewed as an intermediate and a chiral building block for asymmetric synthesis in pharmaceutical and fine chemical manufacturing; it may also serve as a substrate or enzyme assay surrogate in biochemical studies related to metabolic pathways; in analytical chemistry, it can be used as a reference standard for amino acid–related analyses using methods such as HPLC or LC-MS; additionally, as an amino-keto acid, it enables formation of amide-linked derivatives or other synthetic transformations to access higher-value compounds in research and development; its availability as the sodium salt and its synthetic versatility make it a candidate for research, standard material, and applications in life sciences and chemical production.
