Quality Control

Our 1-Isopropyl-2,3-Dimethyl-1-Cyclopentene is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and consistency. We provide full traceability and a Certificate of Analysis (COA) with every shipment, detailing all critical specifications. Our quality system is designed to meet the stringent requirements of cGMP and ISO standards for fine chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat sources and ignition points. Due to its highly volatile nature, keep containers tightly sealed when not in use and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent oxidation or polymerization. Recommended storage temperature is 2-8°C (refrigerated) for optimal stability.
