Quality Control

Our (S)-Methyl-2-Bromo-3-Hydroxypropanoate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity (enantiomeric excess) and chemical purity assays, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing specific results for chiral purity, assay, and impurity profiles are available upon request to support your quality and regulatory documentation.

Storage

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