Quality Control

Our production of 1,3-Dioxane,2,4-Dimethyl-5-(1-Methylethyl)-,(4R,5S)-Rel-(9Ci) adheres to stringent internal quality standards to ensure batch-to-batch consistency and high chemical purity. Each lot is characterized using advanced analytical techniques, including chiral HPLC, to confirm identity, stereochemical purity, and assay. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
