Quality Control

Our (R*,R*)-Pentane-2,4-Diol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by GC or HPLC, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and performance.
