Quality Control

Our Carbamic Acid, Cyclopentyl-, 1,1-Dimethylethyl Ester (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing all test results are provided with every shipment and are available upon request.

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). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from heat, sparks, and open flame.
