Quality Control

Our 1,3-Dioxane is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific batch results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Recommended storage temperature is 2-8°C (36-46°F).
