Quality Control

Our 3-Hexyn-2,5-Diol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets high-purity standards suitable for sensitive synthetic applications. A Certificate of Analysis (COA) detailing specific results for purity, water content, and related substances is provided with every shipment.

Storage

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