Quality Control

Our Methyl (R)-2-Hydroxybutyrate is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including chiral purity analysis by HPLC or GC, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
