Quality Control

Every batch of 6-o-(2-O,3-O,4-O,6-o-Tetraacetyl-α-D-Galactopyranosyl)-β-D-Glucopyranose Tetraacetate is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. We adhere to high standards suitable for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC/NMR), specific rotation, and residual solvent levels is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent hydrolysis of the acetyl groups. For long-term storage, consider desiccant use and an inert atmosphere.
