Quality Control

Our Cyclopentaneacetic Acid, -α--Amino-1-Mercapto- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chiral purity assessment, to ensure it meets the high standards required for research and process chemistry. 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 under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation and light, prolonged exposure to air or light should be avoided. Keep away from incompatible materials such as strong oxidizing agents.
