General description

Acetyl chloride (acyl chloride) is an acetylation reagent used in esterification and Friedel-Crafts acylation reactions.

Application

Acetyl chloride can be used as:
  • A degradation agent in the degradation of polyoxyethylene glycol monoalkyl ethers to determine the degree of ethoxylation using chromatography-mass spectrometry (MS).
  • A reagent with alcohols for the esterification of carboxylic acids, N-boc deprotection, and phosphoramide solvolysis reactions.
