Quality Control

Our 4-Nitrophenyl2-Acetamido-3-o-(2,3,4,6-Tetra-o-Acetyl-B-D-Galactopyranosyl)-2-Deoxy-A-D-Galactopyranoside is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and mass spectrometry, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
