Quality Control

Every batch of Carbamic Acid, (4-Methoxyphenyl)(Methylsulfonyl)-, 1,1-Dimethylethyl Ester (9Ci) is produced and tested under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and batch-to-batch consistency suitable for research and development applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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.
