Application

Acetyl chloride (AcCl) can be used as:
  • An acylating reagent to prepare useful key intermediates in organic synthesis.
  • A reagent to convert oxathioacetals and dithioacetals into corresponding carbonyl compounds in the presence of sodium nitrite.
  • An activating or acylating reagent in solid-phase organic synthesis.
  • A reagent to prepare various alkyl and aryl tetrahydropyranyl ethers from corresponding alcohols.
