Quality Control

Our Carbamicacid,[(1R)-4-[(Methylsulfonyl)Oxy]-1-[[(Methylsulfonyl)Oxy]Methyl]Butyl]-,Phenylmethylester(9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and development. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles, typically determined by advanced analytical techniques like HPLC, NMR, and MS. We adhere to cGMP (current Good Manufacturing Practice) guidelines where applicable to support our clients' regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to prevent degradation. For long-term storage, consider storing under an inert atmosphere such as nitrogen or argon.
