Bromophenol xiav tshuajtseem hu ua tetrabromofluorescein, yog ib qho kev qhia txog cov kua qaub-puag nrog cov yam ntxwv ntawm cov tshuaj tiv thaiv acid-puag. Raws li cov organic dyes, cov mis mos molecular yog C15H9Br4NO5S, CAS 115-39-9. Cov qauv tshuaj muaj xws li lub nplhaib benzene, plaub bromine atoms, sulfonic acid pawg, thiab ib pawg hydroxyl. Bromophenol xiav pH qhia tau tias yog xiav xiav siv lead ua nrog lub siab melting point thiab txheeb ze molecular hnyav. Cov xim sib txawv yuav tshwm sim ntawm pH sib txawv. Nyob rau hauv acidic tej yam kev mob (pH 3.8-5.4), nws tshwm daj; Nyob rau hauv nruab nrab lossis tsis muaj zog alkaline tej yam kev mob (pH 6.5-8.3), nws zoo li ntsuab; Nyob rau hauv muaj zog alkaline tej yam kev mob (pH 9-11), nws tshwm xiav tsaus. Qhov kev hloov xim no yog lub hauv paus rau bromo xiav raws li qhov ntsuas acid-puag. Nws yog ib qho kev ntsuas acid-puag uas tuaj yeem hnov mob nrog cov kua qaub lossis lub hauv paus hloov xim. Nws cov tshuaj tiv thaiv yog thim rov qab, txhais tau tias nws tuaj yeem hloov xim ntawm cov pH sib txawv thiab tuaj yeem rov qab los ntawm ib xim mus rau lwm qhov. Cov tshuaj tiv thaiv rov qab no ua rau nws muaj txiaj ntsig zoo titration tsom xam cov cuab yeej. Feem ntau yog siv rau kev soj ntsuam acid-base titration hauv chav kuaj, bromophenol xiav qhov taw qhia kuj tuaj yeem siv los ua cov xim rau kev sim dyeing thiab cov tshuaj tiv thaiv tshuaj tiv thaiv. Nws yog cov organic dye nrog ntau tus yam ntxwv, feem ntau siv hauv cov tshuaj acid-base titration thiab cov tshuaj tiv thaiv tshuaj tiv thaiv hauv chav kuaj. Nws yog qhov ntsuas pH uas hloov xim ntawm daj mus rau xiav nyob rau hauv pH ntau ntawm 3.{19}} txog 4.6. Nws feem ntau yog siv los ua qhov taw qhia dye rau electrophoresis. Lub electrophoretic migration tus nqi nyob rau hauv gel yog nyob rau hauv cheeb tsam ntawm me me molecule nucleic acid los yog protein.

Muaj peb hom synthesisbromophenol xiav, raws li nram no:
1. dissolve phenol liab nyob rau hauv glacial acetic acid, ntxiv bromine tov nyob rau hauv glacial acetic acid nyob rau hauv stirring, do rau ob peb feeb, ncuav nws mus rau hauv dej kub 60 degrees, txias rau chav tsev kub, thiab muab tso rau ib hmos. Lim, ntxuav lub ncuav mog qab zib nrog glacial acetic acid thiab benzene nyob rau hauv lem, thiab qhuav nws kom tau bromophenol xiav.
2. dissolve phenol liab nyob rau hauv glacial acetic acid, tshav kub rau boiling, poob cov tshuaj bromine yaj nyob rau hauv glacial acetic acid, lim thaum cov khoom daj sib cais, ntxuav tawm cov dawb bromine nrog acetic acid, thiab qhuav nws nyob rau hauv huab cua kom tau. cov khoom nyoos. Ntshiab bromophenol xiav tau los ntawm recrystallization nrog glacial acetic acid los yog tov hnyav ntawm acetone thiab glacial acetic acid.
3. dissolve phenol liab thiab bromine hauv acetic acid los npaj cov tshuaj. Ua ntej, ua kom sov lub phenol liab acetic acid tov rau boiling, thiab ces maj mam ntxiv bromine acetic acid tov nyob rau hauv nplawm: thaum lub phenol liab cov tshuaj tiv thaiv tiav thiab cov daj crystalline hmoov yog tsis precipitated, txias thiab lim. Tom qab ntxuav tawm cov dawb bromine hauv cov siv lead ua nrog me me ntawm acetic acid, recrystallize nrog acetic acid los yog acetone acetic acid, thiab qhuav hauv huab cua kom tau txais cov ntshiab bromophenol xiav.
Bromophenol Blue yog siv dav siv cov kua qaub-puag qhia nrog cov tshuaj tiv thaiv acid-puag cov yam ntxwv.
