Quality Control

Every batch of n-Acetylgalactosaminyl-Alpha(1-3)Galactose is manufactured under strict quality management protocols. We provide comprehensive analytical documentation to ensure product integrity for critical research and development applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) with detailed HPLC purity, NMR confirmation, and residual solvent data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (or as indicated on the label). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under desiccant or inert atmosphere after opening to prevent degradation. For long-term storage, consider freezing at -20°C.
