Quality Control

Our production of Carbamic Acid, [(1S)-1-Methyl-4-Pentenyl]-, 1,1-Dimethylethyl Ester (9Ci) adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC and identity confirmation by NMR and IR spectroscopy, to ensure it meets the exacting standards required for synthetic applications. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles 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 (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
