Quality Control

Our 3-Methyl-1-Cyclopentene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for identity and assay verification. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications and test results to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration of vapors. Recommended storage temperature is 2-8°C (refrigerated) for extended stability.
