Quality Control

Our Tetrahydrofuran (THF) is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We offer various grades, including industrial and high-purity anhydrous grades stabilized with BHT. Certificates of Analysis (COA) detailing purity, water content, peroxide value, and other critical parameters are provided with every shipment to guarantee compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and flammable nature, containers should be kept tightly sealed to prevent evaporation and absorption of moisture. Store away from strong oxidizing agents and acids. Recommended storage temperature is 15-25°C.
