● Siv cov: 2,7-dhihydroxynthhalene tuaj yeem siv los ua cov khoom siv rau cov synthesis ntawm suldonic acids thiab divinylnaphthalses. 2,7-dihydroxynthhalene yog reagent siv nyob rau hauv kev npaj monomers ntawm cov pa roj carbon ntau. Kuj tseem siv nyob rau hauv synthesis ntawm splitomicin analogues. 2,7-naphhalenediol yog reagent siv nyob rau hauv kev npaj Monomers ntawm cov pa roj carbon ntau. Kuj tseem siv nyob rau hauv synthesis ntawm splitomicin analogues.
2,7-dihydroxynthhalene, tseem hu ua Alpha-Naphthol, yog cov organic sib xyaw nrog cov mis molecular c10h8o2. Nws yog ib qho kev ua yeeb yam ntawm Naphhatalene, ib lub caij nyoog muaj ntxhiab hydocarbon.2,7-dhihydroxthhalene yog cov tshuaj dawb los yog soluble solvents xws li ethanol thiab acetone. Nws muaj ob pab pawg hydroxyl txuas nrog cov roj ntsha atoms 2 thiab 7 txoj haujlwm ntawm lub nplhaib naphthalene 2 thiab 7 qhov sib txuas ua ke tau siv nyob rau hauv synthesis ntawm dyes, pigments, thiab kws tshuaj. Nws tseem siv los ua tshuaj lom neeg hauv nruab nrab hauv kev tsim cov tshuaj lom neeg thiab cov tshuaj lom neeg uas tsim nyog, ua haujlwm hauv qhov chaw muaj kev tiv thaiv tus kheej, thiab ua raws cov txheej txheem kom zoo thiab pov tseg.
