Quality Control

Our production of Methyl-3-Isocyanato-3-Phenylpropionate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure high purity and consistency. Certificates of Analysis (COA) documenting all specifications are provided with each shipment 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. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
