Quality Control

Our 3-Ethynyltetrahydrofuran is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) at recommended temperatures between 2°C and 8°C. Keep the container in a cool, dry, well-ventilated place away from heat and ignition sources.
