Quality Control

Our (R)-(+)-1,2-Pentanediol is produced under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) detailing identity, assay, 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, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability. Keep away from strong oxidizing agents.
