Quality Control

Our (S)-2-(1-Methoxy-1-Methylethoxy)-Butanediol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
