Quality Control

Our 3-Hydroxy-2,2-Bis(Hydroxymethyl)Propionaldehyde is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with each shipment to guarantee traceability and consistency.

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, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and degradation.
