Quality Control

Our .Alpha.-L-Galactopyranose, 3,6-Anhydro-4-o-(4-o-Sulfo-.Beta.-D-Galactopyranosyl)-, Homopolymer is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided and can be tailored to support compliance with cGMP, ICH guidelines, and relevant pharmacopeial standards (e.g., USP-NF, EP) upon request.

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 material is hygroscopic (moisture-sensitive) and must be kept in a low-humidity environment to prevent caking and degradation. For long-term storage, consider desiccated conditions.
