Kev siv
N-bromosuccinimide, feem ntau yog ib feem, yog ib qho hmoov zoo crystalline uas yog dawb kom tawm-dawb hauv xim. Nws yog soluble hauv acetone, tetrahydrofformamide, dimethyl sulforoxide, thiab acetorble nyob rau hauv ether, hethane, thiab carbon tetrachloride. NBS feem ntau siv nyob rau hauv qhov dawb radical bromination ntawm allyl thiab benzyl pawg; Lub electrophilic bromination ntawm ketones, cov duab uas muaj ntxhiab, lossis heterocyclic tebchaw; Lub hydroxylation, etheremation, thiab lactonization cov kev tshua ntawm Olefins. NBS yog rhiab rau ya raws thiab yuav tsum muab cia rau hauv lub tub yees. Thaum siv cov txheej txheem, nqus tau lossis sib chwv nrog daim tawv nqaij yuav tsum tau zam, thiab feem ntau ua haujlwm hauv cov hood fume nrog qhov cua zoo.
Siv los ua tus reagent rau kev txheeb xyuas thawj, theem nrab, thiab cov cawv txiv ntoo. Nws tuaj yeem raug siv los ua cov tshuaj bromoacetrile. Hauv kev siv tshuaj tua kab, nws tau siv los ua ke rau hauv cov txiv ntoo, thiab siv cov khoom siv tsis zoo, thiab cov ntaub ntawv pov thawj Nws tuaj yeem siv tau los synthesize bromoacetrile rau tshuaj. Hauv kev siv tshuaj tua kab, nws tau siv los ua ke rau hauv Tswv yim thiab kuj tseem siv tau ua cov txiv ntoo khaws cia, antiseptic, thiab tus neeg sawv cev ua pov thawj. Siv los ua tus reagent rau kev sib koom ua ntej, theem nrab, thiab cov roj hmab rau cov roj hmab, thiab tseem siv hauv cov etthic synthesis. Nws yog ib qho tseem ceeb brominating tus neeg sawv cev hauv synthes artthesis. Hauv kev lag luam kws tshuaj, feem ntau nws siv los ua tus neeg sawv cev brominating nyob rau hauv synthesis ntawm cov tshuaj tua kab mob, xws li cov synthesis ntawm cefaloram. Organic synthesis. Bromination ntawm olefins. Oxidation ntawm ethanol mus rau aldehydes thiab ketones. Oxidation ntawm aldehydes rau bromo - acids. Zov - Muaj nuj nqi brominating tus neeg sawv cev. Nws yog siv nyob rau hauv oxidation tshuaj ntawm Tryptophan, tab sis oxidation degree ntawm tyrosine, thiab cov ntawv seem tsis muaj tsawg. Nws kuj tseem siv tau rau kev hloov kho ntawm Ribosomal Thiol pawg. Nws yog lub universal brominating tus neeg sawv cev. Nyob rau hauv lub xub ntiag ntawm AIBN, SOLLL Cov neeg muaj kev muaj zog tuaj yeem ua rau oxidized rau aldehydes. Nws yog lub universal brominating reagent; siv rau oxidation ntawm tryptophan, txawm hais tias yuav muaj tyrosine, hospidine, thiab cov othionine oxidation seem mus rau ib qho tsawg dua; siv rau cov pab pawg hloov kho ntawm cov pab pawg thiol; Nyob rau hauv lub xub ntiag ntawm AIBN, Silyl Cov neeg txawj ntse yog oxidized rau aldehydes.
