Quality Control

Our Ethanol, 2-[2-[2-(2-Bromoethoxy)ethoxy]ethoxy]- is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including NMR (¹H and ¹³C), HPLC for purity assessment, and Karl Fischer titration for moisture content. A detailed Certificate of Analysis (COA) is supplied with each batch, confirming compliance with specified parameters. Custom synthesis and purification to meet specific research or cGMP-grade requirements are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and incompatible organic solvents. Due to its moisture-sensitive nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
