Quality Control

Our Carbamic Acid, (4-Amino-2-Butenyl)-, 1,1-Dimethylethyl Ester, (E)- (9Ci) is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC, to ensure high chemical purity and isomeric integrity. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request. We can support development projects requiring compliance with cGMP and other regulatory standards.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
