About D-Citrulline

Vaqora Chemicals supplies D-Citrulline, an API reference standard registered under CAS number 13594-51-9. Its molecular formula is C6H13N3O3 and its molecular weight is 175.19 g/mol. The IUPAC name is (2R)-2-amino-5-(carbamoylamino)pentanoic acid. It is also known as H-D-Cit-OH or (R)-2-Amino-5-ureidopentanoic acid.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

As a reference sample of the parent drug substance, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
