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

Umsebenzi

I-N-Bromosuccimide, evame ukufushaniswa njenge-NBS, iyinto enhle ye-crystalline emhlophe yokucisha umbala. Kuyancibilika e-acetone, i-tetrahydroforan, n, n-dimethylformamide, ne-acetonitrile, incibilika kancane emanzini kanye ne-acetic acid, kanye ne-ether, kanye ne-carbon tetrachloride. I-NBS ivame ukusetshenziswa ekuphendukeni kwamahhala kwe-radical brominance kwamaqembu e-alllyl nama-benzyl; ukusabela kwe-electrophilic ama-ketones, amakhompiyutha amnandi, noma amakhompiyutha we-heterocyclic; I-hydroxylation, ukusheshisa, kanye nokuvuka kwe-lactonization of olefin. I-NBS iyazwela umswakama futhi kufanele igcinwe esiqandisini. Ngesikhathi senqubo yokusebenzisa, ukuphefumula noma ukuxhumana nesikhumba kufanele kugwenywe, futhi ngokuvamile kusetshenziswa ku-hood ye-fume ngokusebenza komoya omncane.

Kusetshenziswe njenge-reagent yokuhlonza utshwala obuyisisekelo, kwesekondari, kanye nemfundo ephakeme. Ingasetshenziswa ukuhlanganisa izidakamizwa ze-bromoacetonitritria. Embonini yezibulala-zinambuzane, isetshenziselwa ukuvumelanisa i-thiabendazole futhi futhi ingasetshenziswa njengento yokugcina yezithelo, i-antiseptic, kanye ne-ejenti ye-organic, esetshenziselwa ukukhiqizwa okuphansi, futhi isetshenziswe ekukhiqizweni kwezithasiselo zenjoloba kanye nemithi. Ingasetshenziswa ukuhlanganisa i-bromoetonitritrile yezokwelapha. Embonini yezibulala-zinambuzane, isetshenziselwa ukuvumelanisa i-thiabendazole futhi nayo ingasetshenziswa njengendawo yokugcina yezithelo, i-antiseptic, ne-vent - Kusetshenziswe njenge-realent yokuhlonza utshwala obuyisisekelo, obusekokondali, kanye nezemfundo ephakeme kanye nesengezo semikhiqizo yenjoloba, futhi futhi isetshenziswe ku-organic synthesis. Kuyi-ejenti ebalulekile yokubhaqa e-organic synthesis. Embonini yezemithi, kuvame ukusetshenziswa njenge-ejenti yokuhlasela ekuhlanganiseni kwama-antibiotics, njengokuhlanganiswa kwe-cefaloram. Ukuhlanganiswa okukhohlisayo. Ukugcwala kuka-Olefins. I-Oxidation ye-ethanol kuma-aldehydes nama-ketones. I-Oxidation of Aldehydes to Bromo - Acid. Multi - e-ejenti yokubabaza esebenzayo. Isetshenziswa ekuphendukeni kwe-oxidation ye-tryptophan, kepha i-oxidation degree of tyrosine, i-histidine, nezinsalela ze-methionine kungenzeka ziphansi. Ingase futhi isetshenziselwe ukuguqulwa kwamaqembu we-rubasomal thiol. Kuyi-ejenti yokubamba indawo yonke. Lapho ukhona e-Aibn, uSilyl Talers angakwazi ukufakwa kuma-aldehydes. Kuyindlela yokubhidliza ebonakalayo; isetshenziselwa i-tryptophan, yize kungahle kube khona i-tyrosine, i-histidine, ne-methionine oxidation ezansi kwezinga elincane; isetshenziselwe ukuguqulwa kweqembu kweqembu le-ribosomal thiols; Lapho ekhona e-Aibn, uSilyl, uThembele axididay kuma-Aldehydes.

Ukupakisha nokuthumela

I-25KG / DRUM noma njengezidingo zamakhasimende.
Kungokwezimpahla ezijwayelekile futhi kungahambisa ngo-Ocean nomoya

Gcina futhi ugcine

I-Shelf Life: Inyanga engama-24 kusukela ngosuku lokwenziwa ekuphaketheni kwasekuqaleni okungavunyelwe okugcinwe endaweni epholile eyomile ngaphandle kokukhanya kwelanga, amanzi.
I-Warehouse evutha umoya, ukomisa okushisa okuphansi, okuhlukaniswe nama-oxidants, ama-acid.

I-Warehouse kufanele idlule umoya, igcinwe emazingeni okushisa aphansi bese yomile. Gcina ngokwahlukana kusuka ku-aniline, i-raykyl sulfide, i-hydrazine hydrate, i-peroxides kanye nokuhlolisiswa.
