D-Lysine

About D-Lysine

D-Lysine is a high-purity reference standard of Lysine carrying the CAS registry number 923-27-3. With the molecular formula C6H14N2O2, it has a molar mass of 146.19 g/mol. Its systematic (IUPAC) name is (2R)-2,6-diaminohexanoic acid. Alternative names: (R)-2,6-Diaminohexanoic acid and D-2,6-Diaminohexanoic acid.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Good laboratory practice and suitable PPE are recommended during handling.

Laboratories use this Lysine standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Buyers come mainly from 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.
