Fluoroacetyl chloride(CAS: 359-06-8)

Fluoroacetyl chloride is a colorless or slightly yellow liquid with a molecular weight of 122.54 g/mol. It has a pKa of around 3.5 and is highly soluble in water and organic solvents. It is a strong acid and a potent electrophile, reacting readily with nucleophiles. Proper storage in a cool, dark place away from moisture and heat is necessary due to its reactivity.

Fluoroacetyl chloride is often synthesized via the reaction of acetyl chloride with hydrogen fluoride, followed by dehydration to remove water. Typical yield is around 85-90%, and the process requires careful control of temperature and pressure to ensure high selectivity and yield.

Fluoroacetyl chloride finds application in pharmaceuticals for the synthesis of certain drugs, polymers for functionalization, and sensors for detection of various analytes. It is also used in semiconductor manufacturing for etching and surface modification.

Handling Fluoroacetyl chloride requires strict safety measures. Always wear personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or fume hood to avoid inhalation. Spills should be handled with appropriate absorbents and disposed of according to the SDS. Keep away from heat and moisture sources. Always consult the Safety Data Sheet (SDS) for detailed handling instructions.
