Quality Control

Our 1,3-Epoxy-3-Methylbutane is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of industrial and research applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability to minimize potential polymerization or degradation. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
