Quality Control

Our 2-n-Pentylcyclopentanone is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including GC, IR, and NMR, to verify identity, strength, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided 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 at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening to maintain optimal quality and shelf life. Keep away from heat, sparks, and open flame.
