Quality Control

Our 1,3-Dimethylcyclopentene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, GC-MS, and NMR to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, keep away from heat, sparks, open flames, and oxidizing agents. Minimize exposure to air and moisture during handling.
