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

Kagwiritsidwe Ntchito

N-Bromosuccinimide, yomwe nthawi zambiri imafupikitsidwa kuti NBS, ndi chinthu choyera kwambiri chomwe chimakhala choyera mpaka choyera. Chimasungunuka mu acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, ndi acetonitrile, chimasungunuka pang'ono m'madzi ndi acetic acid, ndipo sichisungunuka mu ether, hexane, ndi carbon tetrachloride. NBS nthawi zambiri imagwiritsidwa ntchito mu free radical bromination reactions ya allyl ndi benzyl groups; electrophilic bromination reactions ya ketones, aromatic compounds, kapena heterocyclic compounds; hydroxylation, etherification, ndi lactonization reactions ya olefins. NBS imakhudzidwa ndi chinyezi ndipo iyenera kusungidwa mufiriji. Pakugwiritsa ntchito, kupuma kapena kukhudzana ndi khungu kuyenera kupewedwa, ndipo nthawi zambiri imagwiritsidwa ntchito mu fume hood yokhala ndi mpweya wabwino.

Amagwiritsidwa ntchito ngati chothandizira kuzindikira mowa woyambira, wachiwiri, ndi wachitatu. Angagwiritsidwe ntchito popanga mankhwala a bromoacetonitrile. Mu makampani opanga mankhwala ophera tizilombo, amagwiritsidwa ntchito popanga thiabendazole ndipo angagwiritsidwenso ntchito ngati chotetezera zipatso, choteteza ku matenda, ndi choteteza ku mildew, ndi zina zotero. Ndi zinthu zopangira zachilengedwe, zomwe zimagwiritsidwa ntchito powongolera zochita za bromination zochepa, komanso zimagwiritsidwanso ntchito popanga zowonjezera za rabara ndi mankhwala. Angagwiritsidwenso ntchito popanga bromoacetonitrile ngati mankhwala. Mu makampani opanga mankhwala ophera tizilombo, amagwiritsidwa ntchito popanga thiabendazole ndipo angagwiritsidwenso ntchito ngati chotetezera zipatso, choteteza ku matenda, ndi choteteza ku mildew. Amagwiritsidwa ntchito ngati chothandizira kuzindikira mowa woyambira, wachiwiri, ndi wachitatu komanso chowonjezera cha zinthu za rabara, komanso amagwiritsidwa ntchito popanga zinthu zachilengedwe. Ndi chinthu chofunikira kwambiri chothandizira kuphatikizika kwa bromination mu kapangidwe ka organic. Mu makampani opanga mankhwala, nthawi zambiri amagwiritsidwa ntchito ngati chothandizira kuphatikizika kwa bromination mu kapangidwe ka maantibayotiki, monga kupanga cefaloram. Kupanga kwachilengedwe. Kuphatikizika kwa olefins. Kusungunuka kwa ethanol ku aldehydes ndi ketones. Kusungunuka kwa aldehydes kukhala ma asidi a bromo. Wothandizira brominating wothandiza kwambiri. Amagwiritsidwa ntchito mu oxidation reaction ya tryptophan, koma kuchuluka kwa oxidation kwa tyrosine, histidine, ndi methionine residues kungakhale kochepa. Angagwiritsidwenso ntchito posintha magulu a ribosomal thiol. Ndi wothandizila brominating wothandiza kwambiri. Pakakhala AIBN, silyl ethers amatha kusungunuka kukhala aldehydes. Ndi wothandizila brominating wothandiza kwambiri; amagwiritsidwa ntchito posungunuka kwa tryptophan, ngakhale kuti pakhoza kukhala tyrosine, histidine, ndi methionine oxidation residues pang'ono; amagwiritsidwa ntchito posintha magulu a ribosomal thiol; pakakhala AIBN, silyl ethers amasungunuka kukhala aldehydes.

Kulongedza ndi Kutumiza

25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.

Nyumba yosungiramo zinthu iyenera kukhala ndi mpweya wokwanira, kusungidwa kutentha kochepa komanso kouma. Sungani padera ndi aniline, dialkyl sulfide, hydrazine hydrate, peroxides ndi propionitrile.
