Quality Control

Our 3,5-Dimethylstyrene Oxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Ensure containers are kept tightly sealed when not in use to prevent evaporation and potential contamination.
