Hydroquinone yog ib yam khoom siv ua kom cov xim dawb uas siv rau hauv cov tshuaj pleev kom dawb. Hydroquinone sib xyaw nrog cov pa oxygen sai heev thiab ua xim av thaum raug cua. Txawm hais tias nws tshwm sim ntuj, cov khoom siv hluavtaws yog qhov feem ntau siv hauv cov tshuaj pleev ib ce. Kev siv rau ntawm daim tawv nqaij yuav ua rau muaj kev tsis haum tshuaj thiab ua rau daim tawv nqaij rhiab heev rau lub hnub. Hydroquinone muaj peev xwm ua rau mob qog noj ntshav thiab cuam tshuam nrog kev ua rau ochronosis, uas yog qhov ua rau daim tawv nqaij tsis zoo. Lub koom haum FDA hauv Tebchaws Meskas tau txwv tsis pub siv hydroquinone los ntawm cov tshuaj pleev ib ce oTC, tab sis tso cai rau 4 feem pua hauv cov khoom lag luam uas tau sau ntawv yuav tshuaj.
1,4-dihydroxybenzene, tseem hu ua hydroquinone, yog ib yam khoom siv tshuaj lom neeg tseem ceeb. Nws zoo li siv lead ua dawb. 1,4-dihydroxybenzene siv dav ua ib yam khoom siv tseem ceeb, tus neeg sawv cev nruab nrab thiab tus neeg sawv cev pabcuam rau tshuaj, tshuaj tua kab, xim thiab roj hmab. Nws feem ntau yog siv ua tus tsim tawm, xim anthraquinone, xim azo, roj hmab antioxidant thiab monomer polymerization inhibitor, zaub mov stabilizer thiab txheej antioxidant, roj av anticoagulant, synthetic ammonia catalyst, thiab lwm yam. Nws kuj tseem siv tau ua analytical reagent, txo tus neeg sawv cev thiab tus tsim tawm ntawm tooj liab thiab kub.
