Quality Control

Our Ethanol, 2-[2-[2-(2-Iodoethoxy)ethoxy]ethoxy]- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for water content, to ensure it meets precise specifications for research and production. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and potential moisture sensitivity, it is recommended to handle under an inert atmosphere for long-term storage and to minimize repeated exposure to air.
