Quality Control

Our 2-Butyn-1-Yl Chloroformate 98 is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis, to ensure it meets the specified 98% minimum purity and is free from critical impurities. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and safety parameters is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and incompatible materials.
