Quality Control

Our Ethyl (2S,3S)-2,3-Epoxy-3-Methylpropanoate is produced under strict quality management protocols to ensure batch-to-batch consistency and high chiral purity. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles. We adhere to cGMP principles where applicable to support our customers' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
