Azelaic acid, yomwe imadziwikanso kuti nonanedioic acid, ndi dicarboxylic acid yodzaza ndi ma formula C9H16O4.Zimawoneka ngati ufa wa crystalline woyera, wopanda fungo, zomwe zimapangitsa kuti zisungunuke mosavuta muzosungunulira zamagulu monga ethanol ndi acetone.Kuphatikiza apo, ili ndi kulemera kwa molekyulu ya 188.22 g/mol.
Azelaic acid yatchuka kwambiri chifukwa cha mitundu yosiyanasiyana ya ntchito m'magawo osiyanasiyana.M'makampani osamalira khungu, amawonetsa mphamvu zolimbana ndi zotupa komanso zotsutsana ndi zotupa, zomwe zimapangitsa kuti ikhale yothandiza pochiza matenda osiyanasiyana akhungu, kuphatikiza ziphuphu, rosacea, ndi hyperpigmentation.Zimathandizira kumasula pores, kuchepetsa kutupa, ndikuwongolera kupanga mafuta ochulukirapo, zomwe zimapangitsa khungu kukhala lowoneka bwino komanso lowoneka bwino.
Kuphatikiza apo, azelaic acid yawonetsa lonjezo muzaulimi ngati bio-stimulant.Kuthekera kwake kukulitsa kukula kwa mizu, photosynthesis, ndi kuyamwa kwa michere muzomera kumapangitsa kuti ikhale chisankho chabwino kwambiri pakuwongolera zokolola komanso mtundu wonse.Itha kugwiritsidwanso ntchito ngati chopondereza champhamvu ku tizirombo tina ta zomera, kuteteza zomera ku matenda.
