Product Information
Description: 2',5'-Dihydroxyacetophenone (DHAP, 2-Acetylhydroquinone, Quinacetophenone) is a mixture of dihydroxyacetophenone isomers used in food flavoring. 2',5'-Dihydroxyacetophenone significantly inhibits the production of NO by inhibiting the expression of iNOS. 2',5'-Dihydroxyacetophenone significantly reduces the expression levels of the pro-inflammatory cytokines TNF-α and IL-6 by blocking the ERK1/2 and NF-κB signaling pathways.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
