Quality Control

Our Cyclopentanecarbonyl Chloride, 3-Pentyl-, trans- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high chemical purity and correct stereochemical configuration. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong bases, oxidizers, and sources of ignition.
