Quality Control

Our Ethylthioethyl Methacrylate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC/HPLC for purity and assay and IR/NMR for structural confirmation, to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, open flames, and strong oxidizing agents.
