Quality Control

Our 1-Ethyl-3-Methylimidazolium (S)-2-Aminopropionate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high chemical purity, chiral integrity, and consistency. Certificates of Analysis (COA) detailing purity, assay, enantiomeric excess, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
