General description
Acetyl chloride is used as an acylating reagent for electrophilic acetylation of alkynes, alkenes, arenes, saturated alkanes, enolates, and organometallics.
Acetyl chloride is a colorless acyl halide. On reaction with ammonia and alcohols, it affords acetamide and esters of acetic acid, respectively. Structural parameters and rotational constants of its isotopic forms have been evaluated from the microwave spectral investigations.

Application
Acetyl chloride has been used in the Lepage and Roy fatty acids analysis, and robotic fatty acid analysis. It may be used for the qualitative in situ synthesis of hydrogen chloride.

Large population studies show that polyunsaturated fatty acids are important for human health, but determining relationships between the health benefits and the fatty acid content has been hampered by the unavailability of labor-effective high-throughput technologies.
