Quality Control

Our (R)-(-)-2-Methyl-2,4-Pentanediol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC or GC, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed specifications for identity, purity, and enantiomeric excess are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
