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

Imikoreshereze

N-Bromosuccinimide, ikunze kuvugwa muri make nka NBS, ni ikintu gito gifite ibara ry’umweru kugeza ku ryera. Irashonga muri acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, na acetonitrile, ishonga gato mu mazi na aside asetiki, kandi ntishonga muri ether, hexane, na tetrachloride ya karuboni. NBS ikunze gukoreshwa mu bikorwa bya bromination bya radical free radical by'amatsinda ya allyl na benzyl; ibikorwa bya bromination bya electrophilic bya ketones, aromatic compounds, cyangwa heterocyclic compounds; ibikorwa bya hydroxylation, etherification, na lactonization bya olefins. NBS ikunda kwitabwaho n'ubushuhe kandi igomba kubikwa muri firigo. Mu gihe cyo kuyikoresha, guhumeka cyangwa gukora ku ruhu bigomba kwirindwa, kandi muri rusange ikorerwa mu gipfundikizo cy'umwuka gifite ubushobozi bwiza bwo guhumeka.

Ikoreshwa nk'ikintu kivura indwara mu kumenya alcool y'ibanze, iya kabiri, n'iya gatatu. Ishobora gukoreshwa mu gukora imiti ya bromoacetonitrile. Mu nganda zivura indwara, ikoreshwa mu gukora thiabendazole kandi ishobora no gukoreshwa nk'ikintu kivura indwara mu mbuto, kirwanya indwara, n'ibindi. Ni igikoresho cy'umwimerere cya synthesis organic, gikoreshwa mu kugenzura uburyo bromination ikoramo ingufu nke, kandi kinakoreshwa mu gukora inyongeramusaruro za rubber n'imiti. Ishobora gukoreshwa mu gukora bromoacetonitrile mu buvuzi. Mu nganda zivura indwara, ikoreshwa mu gukora thiabendazole kandi ishobora no gukoreshwa nk'ikintu kivura indwara mu mbuto, kivura indwara, n'ikintu kivura indwara. Ikoreshwa nk'ikintu kivura indwara mu kumenya alcool y'ibanze, iya kabiri, n'iya gatatu ndetse n'inyongeramusaruro ku bicuruzwa bya rubber, kandi inakoreshwa mu gukora organic synthesis. Ni ikintu cy'ingenzi cya brominating mu gukora organic synthesis. Mu nganda zivura indwara, ikunze gukoreshwa nk'ikintu kivura indwara mu gukora antibiyotike, nko gukora cefaloram. Gukora organic synthesis. Gukora organic bromination ya olefins. Gushyira ethanol muri aldehydes na ketones. Gushyira aldehyde muri aside ya bromo mu mubiri. Brominating agent ifite imikorere myinshi. Ikoreshwa mu gukora oxidation ya tryptophan, ariko urwego rwa oxidation rwa tyrosine, histidine, na methionine residues rushobora kuba ruto. Ishobora kandi gukoreshwa mu guhindura amatsinda ya ribosomal thiol. Ni brominating agent ikoreshwa mu buryo bwose. Iyo AIBN ihari, silyl ethers zishobora gushyirwa oxidation muri aldehydes. Ni brominating reagent ikoreshwa mu buryo bwose; ikoreshwa mu gukora oxidation ya tryptophan, nubwo hashobora kubaho tyrosine, histidine, na methionine residues ku rugero ruto; ikoreshwa mu guhindura amatsinda ya ribosomal thiol; iyo AIBN ihari, silyl ethers zishyirwa oxidation muri aldehydes.

Gupakira no Kohereza

25KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere

Bika kandi ubibike

Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.

Ububiko bugomba kuba bufite umwuka uhumeka, bugashyirwa ku bushyuhe buke kandi bwumutse. Bubike ukwabwo na aniline, dialkyl sulfide, hydrazine hydrate, peroxide na propionitrile.
