Mwachidule p-hydroxyacetophenone, chifukwa molekyu yake imakhala ndi magulu a hydroxyl ndi ketone pa mphete ya benzene, choncho nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati pakupanga organic kuti agwirizane ndi mankhwala ena kuti apange zinthu zambiri zofunika. Nthawi zambiri ntchito synthesis wa intermediates mankhwala (α-bromo-p-hydroxyacetophenone, choleretic mankhwala, antipyretic analgesics ndi mankhwala ena), Other (zonunkhira, chakudya, etc.; Mankhwala, utoto, madzi galasi zipangizo, etc.).
Kugwiritsa ntchito p-hydroxyacetophenone ndi woyera singano ngati krustalo kutentha firiji, mwachibadwa zimachitika mu zimayambira ndi masamba a Artemisia scoparia, mu mizu zomera monga ginseng mwana Vine. Itha kugwiritsidwa ntchito popanga mankhwala a choleretic ndi zida zina zopangira organic synthesis.
