Quality Control

Our n-Acetylneuraminyl-(2-3)-Galactose is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and specific tests for residual solvents and moisture. Certificates of Analysis (COA) with detailed chromatograms and spectral data are provided to ensure traceability and compliance with research-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic (moisture-sensitive) nature, allow the sealed container to equilibrate to room temperature before opening to prevent condensation. For long-term storage, consider under inert atmosphere.
