1,7-dihydroxynthhalene, tseem hu ua Naphthalene-1,7-Diol, yog cov organic sib xyaw nrog cov mis molecular c10h8o2. Nws yog ib qho kev ua yeeb yam ntawm naphthalene, ib lub caij tsheb kauj vab hydrocarbon.1,7-dihydroxthhalene yog cov tshuaj dawb lossis tawv nqaij uas yog cov kuab tshuaj yeeb zoo ib yam li ethanol thiab acetone. Nws muaj ob pawg hydroxyl txuas nrog cov roj carbon atoms 1 thiab 7 txoj haujlwm ntawm lub nplhaib naphthalal.Qhov zoo li nws isomer, 1,7-dihyrdoxynthhalene kuj pom cov ntawv thov hauv cov organic synthesis. Nws tuaj yeem raug siv los ua lub tsev thaiv cov khoom siv rau ntau yam sib xyaw, suav nrog cov duab paug, tshuaj, thiab cov tshuaj tua kab mob thiab tiv thaiv cov khoom. Nws yog paub rau scavenenge dawb radicals thiab nthuav tawm cov peev xwm kho tau. Nws raug nquahu kom siv cov khoom tiv thaiv tiv thaiv, ua haujlwm hauv qhov chaw muaj pa zoo, thiab ua raws cov txheej txheem uas tsim nyog thiab pov tseg thaum ua haujlwm nrog cov compound no.
