Quality Control

Our Carbamic Acid, (2-Chloro-2-Oxoethyl)-, 1,1-Dimethylethyl Ester (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR), to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect product stability and performance.
