Azelaic acid yog cov organic sib xyaw nrog cov mis (CH2) 7 (CO2H) 2. Qhov saturated dicarboxylic acid tshwm sim ua hmoov dawb. Nws muaj nyob hauv cov nplej, rye, thiab barley. Nws yog ib qho ua ntej rau ntau yam khoom lag luam suav nrog polymers, yas yas, ntxiv rau ua ib feem ntawm cov plaub hau thiab tawv nqaij txias.

Azelaic acid yog tshuaj tiv thaiv kab mob ntawm daim tawv nqaij thiab siv tshuaj kho mob, feem ntau yog siv rau kev kho pob txuv, chloasma thiab tawv nqaij melanin tso. Nws kuj tseem yog ib qho tseem ceeb organic sib xyaw ua ke nruab nrab, siv hauv yas, roj hmab thiab lwm yam lag luam rau kev sib xyaw ua cov yas, hauv cov aviation roj rau kev sib xyaw ntawm qhov kub thiab txias kom nrawm rau roj, electrolytic capacitor manufacturing thiab lwm yam ntawm cov ntawv tseem ceeb. Tam sim no, txoj hauv kev tsim khoom tseem ceeb yog npaj azelaic acid los ntawm cov rog tsis muaj roj xws li oleic acid thiab sib thooj triglycerides xws li roj castor thiab roj cottonseed. Feem ntau ntawm azelanoic acid tau siv hauv kev tsim cov tshuaj yas dioctyl azelanoate (DOZ), thaum lwm qhov siv yog cov txuj lom, roj nplua nyeem, roj, thiab cov khoom siv raw ntawm polyamide resins. DOZ kuj tseem tuaj yeem siv ua cov softener rau hluavtaws roj hmab. Tus nqi ntawm azelaic acid siv los tsim DOZ hauv Nyij Pooj suav txog li 70% ntawm kev siv tag nrho ntawm azelaic acid. Azelaic acid tuaj yeem ua kom lub cev qhuav dej los ntawm ammonia los tsim Azelaic nitrile. Siv rau kev tsim cov yas yas dioctyl azelanoate thiab txuj lom, lubricating roj, roj, thiab polyamide cob cov khoom siv raw. Siv los ua cov tshuaj reagent thiab tseem yog cov organic sib txuas.
