Quality Control

Our Cyclopropanecarboxylic Acid, 1-Amino-2-(1-Methylethyl)-, trans- (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure high chemical purity, correct stereochemistry, and consistent performance as a synthesis intermediate. Certificates of Analysis (COA) detailing identity, purity (HPLC/Chiral HPLC), and impurity profiles are provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and potential degradation. Recommended long-term storage temperature is 2-8°C.
