Quality Control

Our 3,4,6-Tri-o-Acetyl-α-D-Galactopyranose 1,2-(Methyl Orthoacetate) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and optical rotation analysis, to ensure high chemical purity and stereochemical integrity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and compliance with your research or cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption and decomposition. Keep away from strong oxidizing agents.
