Quality Control

Our 1-Sila-3-Cyclopentene 95% is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity and assay specifications. Certificates of Analysis (COA) detailing purity, physical properties, and test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
