Quality Control

Our Carbamic Acid, (1-Ethyl-3-Hydroxypropyl)-, 1,1-Dimethylethyl Ester (9Ci) is produced under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided with each shipment, detailing all critical specifications. We support compliance with REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) for long-term storage to prevent degradation. Keep away from heat and incompatible materials.
