Quality Control

Our Z-D-Lys(Boc)-Osu is manufactured under strict quality systems to ensure batch-to-batch consistency and high purity for sensitive applications. Products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each batch to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. For long-term storage, consider storing under an inert atmosphere.
