Quality Control

We supply (R)-1,2-Epoxypentane in high-purity grades suitable for demanding synthetic applications. Our products undergo rigorous quality testing, including chiral purity analysis by GC or HPLC, to ensure compliance with research and development standards. A comprehensive Certificate of Analysis (COA) detailing assay, enantiomeric excess (ee), and impurity profile is provided with each batch to guarantee traceability and performance consistency.

Storage

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