Description
Acetylacetone (CAS 123-54-6), also known as ACAC, Hacac, or 2,4-pentanedione, is a beta-diketone organic compound registered under EC 204-634-0 with FEMA number 2841. It carries no E-code designation and is classified within the organic acids category for commercial supply purposes.
In polymer and coatings manufacturing, acetylacetone acts as a crosslinking agent by coordinating with metal ions to form stable chelate complexes that cure resin systems. In food and fragrance applications, it functions as a flavoring agent at controlled concentrations, contributing buttery and caramel-like notes. It also serves as a ligand precursor in catalytic processes, particularly in metal-organic synthesis.
Acetylacetone is supplied in liquid form and is available in technical and food-grade specifications compliant with FCC standards. It falls under REACH regulation and requires standard SDS documentation for EU trade. Typical packaging includes drums and IBC containers, with HS code 29141900 applicable for import and export classification.
