Description
DL-Citrulline (CAS 627-77-0, EC 211-012-2) is the racemic form of the non-proteinogenic amino acid citrulline, abbreviated as Cit. It carries no assigned E-code. It is also referenced under the synonyms H-DL-Cit-OH, (±)-Citrulline, and NSC 46711.
In pharmaceutical and nutraceutical formulations, DL-Citrulline serves as a precursor to arginine in the urea cycle, supporting nitric oxide synthesis pathways relevant to cardiovascular and sports nutrition products. In biotechnology, it functions as a biochemical reference standard and metabolic tracer in enzyme activity assays targeting the urea cycle and citrullination reactions.
DL-Citrulline is available in reagent and nutritional grades as a white crystalline powder. It falls under REACH registration requirements for EU supply and may be sourced to FCC specifications for food and supplement applications. Packaging is typically offered in laboratory quantities through to multi-kilogram formats for industrial use.
