Quality Control

Our Glycol Aldehyde Dimer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment.

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). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
