N-Bromosuccinimide/NBS/CAS: 128-08-5

Kev Siv

N-Bromosuccinimide, feem ntau hu ua NBS, yog ib yam khoom siv crystalline zoo uas muaj xim dawb mus rau dawb tawm. Nws yaj tau hauv acetone, tetrahydrofuran, N, N-dimethylformamide, dimethyl sulfoxide, thiab acetonitrile, yaj me ntsis hauv dej thiab acetic acid, thiab tsis yaj hauv ether, hexane, thiab carbon tetrachloride. NBS feem ntau siv rau hauv cov tshuaj tiv thaiv bromination dawb ntawm allyl thiab benzyl pawg; cov tshuaj tiv thaiv bromination electrophilic ntawm ketones, aromatic compounds, lossis heterocyclic compounds; cov tshuaj hydroxylation, etherification, thiab lactonization ntawm olefins. NBS rhiab heev rau cov dej noo thiab yuav tsum khaws cia rau hauv lub tub yees. Thaum lub sijhawm siv, yuav tsum tsis txhob ua pa lossis kov daim tawv nqaij, thiab feem ntau nws ua haujlwm hauv lub qhov cub fume nrog kev ua haujlwm zoo.

Siv ua ib yam khoom siv los txheeb xyuas cov cawv thawj, theem ob, thiab theem peb. Nws siv tau los tsim cov tshuaj bromoacetonitrile. Hauv kev lag luam tshuaj tua kab, nws siv tau los tsim thiabendazole thiab kuj siv tau ua cov tshuaj tiv thaiv txiv hmab txiv ntoo, tshuaj tua kab mob, thiab cov tshuaj tiv thaiv pwm, thiab lwm yam. Nws yog cov khoom siv organic synthesis, siv los tswj cov tshuaj tiv thaiv bromination qis zog, thiab tseem siv rau hauv kev tsim cov roj hmab ntxiv thiab tshuaj. Nws siv tau los tsim bromoacetonitrile rau tshuaj. Hauv kev lag luam tshuaj tua kab, nws siv tau los tsim thiabendazole thiab kuj siv tau ua cov tshuaj tiv thaiv txiv hmab txiv ntoo, tshuaj tua kab mob, thiab cov tshuaj tiv thaiv pwm. Siv ua ib yam khoom siv los txheeb xyuas cov cawv thawj, theem ob, thiab theem peb thiab cov tshuaj ntxiv rau cov khoom roj hmab, thiab kuj siv rau hauv kev tsim cov organic. Nws yog ib yam khoom siv tseem ceeb hauv kev tsim cov organic. Hauv kev lag luam tshuaj, nws feem ntau siv ua tus neeg sawv cev brominating hauv kev tsim cov tshuaj tua kab mob, xws li kev tsim cefaloram. Kev tsim cov organic. Kev tsim olefins. Kev tsim ethanol rau aldehydes thiab ketones. Kev Oxidation ntawm aldehydes rau bromo-acids. Tus neeg sawv cev brominating ntau yam. Nws yog siv rau hauv qhov kev tshuaj tiv thaiv oxidation ntawm tryptophan, tab sis qib oxidation ntawm tyrosine, histidine, thiab methionine residues yuav qis heev. Nws kuj tseem siv tau rau kev hloov kho ntawm ribosomal thiol pawg. Nws yog tus neeg sawv cev brominating thoob ntiaj teb. Nyob rau hauv lub xub ntiag ntawm AIBN, silyl ethers tuaj yeem oxidized rau aldehydes. Nws yog ib qho reagent brominating thoob ntiaj teb; siv rau kev oxidation ntawm tryptophan, txawm hais tias tej zaum yuav muaj tyrosine, histidine, thiab methionine oxidation residues rau qee qhov tsawg dua; siv rau kev hloov kho pawg ntawm ribosomal thiol pawg; nyob rau hauv lub xub ntiag ntawm AIBN, silyl ethers raug oxidized rau aldehydes.
