2-Naphthylamine CAS 91-59-8 Purity > 98.0% (HPLC)

2-Naphthylamine (CAS: 91-59-8) yog teeb meem, carcinogenic, International Institute for Cancer Research (IARC) muab benzidine, 2-Naphthylamine thiab 4-Aminobiphenyl raws li tib neeg carcinogen (cov pov thawj), peb yuav tsum tau ceev faj tshwj xeeb.Nws yog insoluble hauv dej, tab sis soluble hauv dej kub, ethanol, ether thiab benzene thiab lwm yam. Aqueous tov yog xiav fluorescence.Nws tuaj yeem raug txo los ntawm tshav kub nyiaj nitrate ammonia tov.Nws yog synthesized los ntawm 2-naphthol nrog ammonia thiab ammonium sulfite nyob rau hauv lub siab kub system.2-Naphthylamine yog ib qho tseem ceeb dye intermediates, tuaj yeem siv rau hauv kev tsim cov dyes, phthalocyanine dyes, reactive dyes (Reactive ci ntsa iab txiv kab ntxwv K-7R, active golden XG, active golden KM-G, Reactive Yellow KM-RN, pawg liab loj B) thiab J acid.Nws kuj tseem siv tau los ua cov tshuaj ntsuam xyuas cov organic thiab cov ntsuas fluorescent, thiab tseem yog cov khoom siv hluavtaws.Amino thiab nitrite ntawm Aminonaphthalene tuaj yeem tsim diazonium ntsev, thiab tuaj yeem hloov mus rau ntau yam hydrocarbon derivatives ntawm naphthalene, nws tuaj yeem siv rau hauv kev tsim cov dyes thiab organic synthesis, kuj tseem siv los ua cov cim ntawm cov organic analytical reagents thiab fluorescent agents.Nws yog teev raws li ib tug paub neeg carcinogen.Siv rau hauv kev tsim cov dyes, ua antioxidant hauv roj hmab.Nws yog ib qho nruab nrab hauv kev npaj ntawm lwm cov tebchaw.Nws siv yog txwv tsis pub vim muaj kev phom sij rau kev noj qab haus huv.Cov cuab yeej tsim khoom yuav tsum raug kaw kom nruj kom tsis txhob muaj kev khiav tawm ntawm cov pa phem thiab plua plav.
