Quality Control

Our 3,6-Dimethyl-1,4-Dioxane-2,5-Dione Homopolymer is manufactured under strict quality management systems. Each batch is characterized for critical parameters including inherent viscosity, molecular weight distribution, residual monomer content, and thermal properties to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant pharmaceutical (ICH Q3) and medical device regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under dry conditions to prevent hydrolysis and molecular weight degradation. For long-term storage, consider using desiccants or inert atmosphere packaging.
