Quality Control

Our 2-Butyne-1,4-Diol Diglycerol Ether is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, water content, and specific impurities are provided and available upon request, supporting your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids, organic solvents, and sources of ignition. Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature: 2-25°C.
