Calcium acetylacetonate

Calcium acetylacetonate (CA-ACAC, CAS 19372-44-2) is the calcium salt of acetylacetone, also known as calcium 2,4-pentanedionate or bisacetylacetonatocalcium. It carries no assigned E-code and is classified under HS code 29141900. The compound is commercially handled as a dry powder.

In polymer and elastomer formulations, CA-ACAC functions as a crosslinking agent by coordinating with reactive polymer chains through its chelated calcium center, improving network density and mechanical performance. In food and fragrance applications, it contributes acetylacetone-derived flavor and aroma notes. It also serves as a catalyst or catalyst precursor in select organic synthesis processes.

CA-ACAC is supplied as a powder and is subject to REACH registration requirements within the European Economic Area. Buyers should confirm food-contact or flavor-use compliance against applicable FCC or regional food additive frameworks, as no harmonized E-code exists. Standard industrial packaging applies; consult supplier documentation for available lot sizes and specifications.
