Quality Control

Our Butane-1,3-Diol: Hexanedioic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in hydroxyl value, acid value, molecular weight distribution, and viscosity. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
