Quality Control

Our o-(5-Acetamido-3,5-Didesoxyglycerogalacto-2-Nonuloyranosyluronic)-(2-3)-o-Galactoyranosyl-(1-3)-2-Acetamido-2-Desoxygalactopyranose is produced under strict quality management systems suitable for research and development. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (HPLC), optical rotation, and moisture content are available upon request. We support compliance with relevant standards for biochemical reagents.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under dry, inert conditions if possible. For long-term stability, store at -20°C or below. Allow the product to equilibrate to room temperature in a dry environment before opening to prevent condensation and moisture uptake.
