Quality Control

Our 3-Cyclopentene-1,3-Dicarboxylic Acid, 1,2,2-Trimethyl-, (R)- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) detailing identity, purity, and chiral excess 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, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
