Quality Control

Our Pyrrolidine, 2-(1E)-1-Butenyl- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC and GC, to ensure compliance with exacting research and process chemistry standards. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic 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.
