Quality Control

Our 1-Bromo-2-Pentene is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, assay, and impurity profile. Certificates of Analysis (COA) documenting these results are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and bases. Recommended storage temperature is 2-8°C for extended stability. Keep container tightly sealed when not in use to minimize moisture absorption and volatilization.
