Quality Control

Our Oxirene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee it meets your precise specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flames.
