Quality Control

Our production of Dodecyl (3-Isocyanato-4-Methylphenyl)-Carbamate adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by HPLC, determination of isocyanate content, and impurity profiling. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture ingress. Isolate from strong bases, acids, and other reactive materials.
