Quality Control

Our (2R,3R)-2,3-Epoxybutane Trans is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by GC or HPLC, to ensure compliance with exacting standards for research and industrial use. Certificates of Analysis (COA) detailing identity, purity, enantiomeric excess, 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, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed. Recommended storage temperature is 2-8°C for long-term stability, although it may be stored at controlled room temperature for short periods. Keep away from strong acids, bases, and oxidizing agents.
