    Acetylacetone CAS 123-54-6

    Acetylacetone CAS 123-54-6 is a bifunctional organic compound belonging to the beta-diketone class, widely utilized as a chemical building block in the production of heterocyclic compounds and metal acetylacetonate catalysts. Chemically identified as 2,4-Pentanedione, this liquid exhibits keto-enol tautomerism, a property that makes it a highly effective ligand for coordinating with transition metals in industrial catalysis and extraction processes. The solvent, also known as diacetylmethane, is essential in the synthesis of sulfonamides, pesticides, and corrosion inhibitors for lubrication systems. We provide competitive factory pricing and flexible options for customized specifications to meet various purity grades. Our bulk supply is supported by comprehensive regulatory documents, including MSDS, TDS, COA, to ensure safe and compliant industrial usage.

    FAQ - Technical & Supply Chain

    • Q:

      Does this product correspond to the standard beta-diketone used for metal chelation?

      A: Yes, Acetylacetone (CAS 123-54-6) is the specific 2,4-Pentanedione isomer used extensively to form stable metal acetylacetonate complexes in catalyst manufacturing and metal extraction.
    • Q:

      Is acetylacetone intended for industrial formulations rather than laboratory-only use?

      A: Acetylacetone is commonly used as an industrial chemical intermediate and chelating agent in process‑level applications, including catalyst and coordination compound preparation, beyond laboratory research contexts.
