Quality Control

Our Ethaneperoxoic Acid, 2-Hydroxycyclopentyl Ester (9Ci) is manufactured under strict quality protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed to confirm identity, purity, and stability. Certificates of Analysis (COA) detailing specific test results are provided with every shipment 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 heat, sparks, and incompatible materials. Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive, we recommend storage under an inert atmosphere such as nitrogen and at controlled room temperature (15-25°C).
