Quality Control

Our trans-β-Butylene Oxide is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including Gas Chromatography (GC) for purity and isomer content verification. A Certificate of Analysis (COA) detailing specific results for identity, assay, and impurities is supplied with each shipment 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 ignition points. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration of vapors. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable. Keep away from strong acids, bases, and oxidizing agents.
