Quality Control

Every batch of 1-Cyclopentene-1-Carboxaldehyde, 3-(Hydroxymethyl)- (9Ci) is produced and tested under strict quality management protocols to ensure consistency and purity for sensitive synthetic applications. Our standard grade meets high-purity research specifications, with comprehensive analytical data provided. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for all shipments upon request. We support custom synthesis and can tailor specifications to meet specific project requirements, including compliance with cGMP standards for advanced pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation. Keep away from strong oxidizing agents.
