Product Nature:

Dibenzoylmethane is a trace component of licorice that activates Nrf2 and can prevent various cancers and oxidative damage. Dibenzoylmethane is an analogue of curcumin, which causes the dissociation of Keap1 and the nuclear translocation of Nrf2.

Product Usage:

  • Dibenzoylmethane, also known as 1,3-diphenyl-1,3-propanedione, has tautomers and can absorb ultraviolet light above 290nm. At present, it is mainly used as a feed additive. The synthesis of dibenzoylmethane can be obtained by condensing ethyl benzoate with acetophenone in the presence of sodium ethoxide. It is used as a precious metal extractant and a reagent for the determination of carbon disulfide and rafts.

  • Dibenzoylmethane can react with many metal ions to form corresponding metal chelate compounds such as: Ag.Ga, Bi, La, Mo, Sr and so on. These metal chelates can be extracted by organic solvents such as benzene, ethyl acetate, butyl acetate, etc., and can be used as extraction photometric reagents for these metal ions.

  • In the past ten years, its application range has gradually expanded, such as: as an additive to PVC to improve its thermal stability and so on. Therefore, people’s demand for dibenzoylmethane has greatly increased, and there is a good development prospect.
