Incamake p-hydroxyacetophenone, kubera ko molekile yayo irimo hydroxyl na ketone kumatsinda ya benzene, kubwibyo rero, ikoreshwa kenshi nkigihe gito muri synthesis organique kugirango ikore hamwe nibindi bintu kugirango ihuze ibintu byinshi byingenzi. Mubisanzwe bikoreshwa muguhuza imiti ihuza imiti (α-bromo-p-hydroxyacetophenone, imiti ya choleretique, imiti igabanya ubukana nindi miti), Ibindi (ibirungo, ibiryo, nibindi.; Imiti yica udukoko, amarangi, ibikoresho bya kirisiti byamazi, nibindi).
Gusaba p-hydroxyacetophenone ni urushinge rwera rumeze nka kirisiti yubushyuhe bwicyumba, mubisanzwe biboneka mumuti namababi ya Artemisia scoparia, mumuzi yibimera nka ginseng umwana Vine. Irashobora gukoreshwa mugukora imiti ya kolera nibindi bikoresho fatizo bya synthesis.
