Quality Control

Our 6-o-Carboxymethyl-n-Acetyl-1,4-Polygalactosamine is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, degree of substitution, and functional performance. Certificates of Analysis (COA) detailing key parameters such as assay, degree of carboxymethylation, and viscosity are available upon request. We can support development of specifications aligned with cGMP or other relevant quality standards for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance.
