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

Isticmaalka

N-Bromosuccinimide, oo inta badan loo soo gaabiyo NBS, waa walax crystalline ah oo midabkeedu yahay caddaan ilaa caddaan. Waxay ku milmi kartaa acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, iyo acetonitrile, oo si yar ugu milmi karta biyaha iyo acetic acid, oo aan ku milmi karin ether, hexane, iyo kaarboon tetrachloride. NBS waxaa badanaa loo isticmaalaa falcelinta bromination-ka xorta ah ee kooxaha allyl iyo benzyl; falcelinta bromination-ka ee electrophilic ee ketones, isku-dhafka aromatic, ama isku-dhafka heterocyclic; falcelinta hydroxylation, etherification, iyo lactonization ee olefins. NBS waxay u nugul tahay qoyaanka waana in lagu kaydiyaa qaboojiyaha. Inta lagu jiro habka isticmaalka, waa in laga fogaadaa neefsashada ama taabashada maqaarka, waxaana guud ahaan lagu shaqeeyaa daboolka qiiqa oo leh waxqabad hawo-qaadis oo wanaagsan.

Waxaa loo isticmaalaa sidii reagent si loo aqoonsado khamriga aasaasiga ah, kan labaad, iyo kan saddexaad. Waxaa loo isticmaali karaa in lagu sameeyo daawooyinka bromoacetonitrile. Warshadaha cayayaanka, waxaa loo isticmaalaa in lagu sameeyo thiabendazole waxaana sidoo kale loo isticmaali karaa sidii ilaaliye miro, jeermis dile, iyo wakiil caariyaysi ah, iwm. Waa walxo ceeriin ah oo isku-darka organic-ga ah, oo loo isticmaalo in lagu xakameeyo falcelinta bromination-ka tamarta yar, sidoo kale waxaa loo isticmaalaa soo saarista waxyaabaha lagu daro caagga iyo daawooyinka. Waxaa loo isticmaali karaa in lagu sameeyo bromoacetonitrile daawada. Warshadaha cayayaanka, waxaa loo isticmaalaa in lagu sameeyo thiabendazole waxaana sidoo kale loo isticmaali karaa sidii ilaaliye miro, jeermis dile, iyo wakiil caariyaysi ah. Waxaa loo isticmaalaa sidii reagent si loo aqoonsado khamriga aasaasiga ah, kan labaad, iyo kan saddexaad iyo wax lagu daro waxyaabaha caagga ah, sidoo kale waxaa loo isticmaalaa isku-darka organic-ga. Waa wakiil brominating muhiim ah oo ku jira isku-darka organic-ga. Warshadaha dawooyinka, waxaa badanaa loo isticmaalaa sidii wakiil brominating ah oo ku jira isku-darka antibiyootigyada, sida isku-darka cefaloram. Isku-darka organic-ga. Bromination of olefins. Oxidation of ethanol to aldehydes and ketones. Oxidation of aldehydes to bromo - acids. Brominating multi-functional. Waxaa loo isticmaalaa falgalka oksaydhka ee tryptophan, laakiin heerka oksaydhka ee haraaga tyrosine, histidine, iyo methionine ayaa laga yaabaa inay yar tahay. Waxa kale oo loo isticmaali karaa wax ka beddelka kooxaha ribosomal thiol. Waa wakiil brominating caalami ah. Joogitaanka AIBN, silyl ethers waxaa lagu oksaydhi karaa aldehydes. Waa fal-gal brominating caalami ah; waxaa loo isticmaalaa oksaydhka tryptophan, inkastoo ay jiri karaan haraaga oksaydhka tyrosine, histidine, iyo methionine ilaa xad yar; waxaa loo isticmaalaa wax ka beddelka kooxda ee kooxaha ribosomal thiol; joogitaanka AIBN, silyl ethers waxaa lagu oksaydhiyaa aldehydes.
