Quality Control

Our 1-Cyclopentene-1-Carbonitrile, 2-(1,2-Propadienyl)- (9Ci) is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC and NMR, to verify identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters 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 place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
