Quality Control

Our 2,5-Dimethyl-3,4-Hexanediol is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, enantiomeric/diastereomeric purity, and moisture content are available upon request. We adhere to cGMP principles where applicable to meet the stringent requirements of our pharmaceutical and advanced material customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent moisture absorption and potential degradation.
