Diethylaminosulfur Trifluoride (DAST), a powerful and versatile fluorinating agent, is an invaluable tool in modern synthetic chemistry. However, its efficacy is matched by its hazardous nature, necessitating strict adherence to safety protocols during handling and storage. Understanding these precautions is paramount for any laboratory that utilizes this compound, identified by its CAS number 38078-09-0.

DAST is a flammable liquid that is corrosive and can cause severe skin burns and eye damage. It is also harmful if inhaled or swallowed. Due to its reactivity, it is incompatible with water, glass, and certain other materials, which can lead to hazardous decomposition. Therefore, when working with DAST, it is crucial to ensure adequate ventilation, ideally within a fume hood, and to wear appropriate personal protective equipment (PPE). This includes chemical-resistant gloves (such as nitrile or neoprene), safety goggles or a face shield, and a lab coat. Researchers often consult safety data sheets when they are ready to buy diethylaminosulfur trifluoride to familiarize themselves with the specific hazards.

Storage of DAST requires special attention. It should be kept in a tightly sealed container in a cool, dry, and well-ventilated area, away from incompatible substances and sources of ignition. Many suppliers recommend storing DAST at temperatures below 0°C to maintain its stability. Proper labeling of the storage area and containers is also essential. The detailed DAST chemical properties include its instability under certain conditions, which underscores the need for careful storage.

In the event of exposure or an accident, immediate action is critical. For skin contact, affected areas should be flushed with copious amounts of water. If DAST is inhaled, the person should be moved to fresh air. In case of eye contact, rinsing with water for several minutes is necessary, and medical attention should be sought immediately for any significant exposure. Spill containment procedures should be in place, and appropriate neutralizing agents, if recommended by the SDS, should be readily available.
