DL-citrulline

DL-Citrulline (CAS 627-77-0) is the racemic form of the non-essential amino acid citrulline, distinct from the naturally occurring L-isomer. It functions as a biochemical intermediate and building block in pharmaceutical synthesis, peptide chemistry, and nutritional research applications.

In pharmaceutical development, this compound serves as a synthetic intermediate for producing citrullinated peptides used in autoimmune disease research. This includes assay development for rheumatoid arthritis diagnostics and other clinical screening tools.

Peptide synthesis workflows use it as a racemic reference standard or precursor where stereospecificity is not required. This application helps in reducing input costs during early-stage screening and laboratory testing phases.

In nutritional science and functional food research, it supports formulation studies examining urea cycle metabolism and amino acid bioavailability. Biotechnology labs also use it as a substrate or reference compound in enzyme activity assays.

These assays often target argininosuccinate synthetase and related metabolic pathways within the body. The compound is typically supplied as a white crystalline powder in research and commercial quantities for industrial use.

It is available in reagent-grade and pharmaceutical-grade specifications, with purity levels commonly at 98% or higher by HPLC. Our material meets rigorous internal quality standards to ensure consistency across different production batches.

Packaging ranges from small laboratory quantities to bulk orders, depending on specific application requirements. We ensure that all shipments are handled according to strict safety and storage protocols for chemical distribution.
