Quality Control

Our trans-3,4-Dimethylcyclopentene is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure high chemical purity and isomeric integrity. A detailed Certificate of Analysis (COA) confirming identity, purity, and impurity profile is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed at temperatures between 2°C and 8°C to maximize stability and shelf life. Keep away from heat, sparks, and open flame.
