  • Applications

    Acetyl iodide (CAS 507-02-8) is a reactive acyl halide primarily used as an acetylating reagent in organic synthesis. Typical applications include acetylation of hydroxyl groups (alcohols) and phenols as well as amino groups to form acetyl esters and acetylated derivatives; serving as a reagent to prepare acetylated intermediates in pharmaceuticals and fine chemicals; participating in polymer synthesis to introduce acetyl groups to tailor material properties; and used as an intermediate to generate other acetyl derivatives or acyl iodides for subsequent synthetic routes. Use is subject to local regulations and formulation limits.
