Quality Control

Our 1,3,5-Trioxane is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous specifications for identity, assay, and impurity profiles. Certificates of Analysis (COA) documenting purity, moisture content, and other critical parameters are available for every shipment 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 for long-term stability and to minimize sublimation. Keep container tightly sealed when not in use.
