Quality Control

Our Cyclopropanecarboxylic Acid, 1-Amino-2-Ethyl-, (1R,2R)-Rel- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing identity, purity, and chiral excess are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. 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. Recommended long-term storage temperature is 2-8°C.
