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

Amfani

N-Bromosuccinimide, wanda aka fi sani da NBS, wani sinadari ne mai kyau na crystalline wanda launinsa fari ne zuwa fari. Yana narkewa a cikin acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, da acetonitrile, yana narkewa kaɗan a cikin ruwa da acetic acid, kuma ba ya narkewa a cikin ether, hexane, da carbon tetrachloride. Sau da yawa ana amfani da NBS a cikin halayen bromination masu tsattsauran ra'ayi na allyl da benzyl; halayen bromination na electrophilic na ketones, mahaɗan aromatic, ko mahaɗan heterocyclic; halayen hydroxylation, etherification, da lactonization na olefins. NBS yana da sauƙin kamuwa da danshi kuma ya kamata a adana shi a cikin firiji. A lokacin amfani, ya kamata a guji shaƙa ko taɓa fata, kuma gabaɗaya ana aiki da shi a cikin murfin hayaki tare da ingantaccen aikin iska.

Ana amfani da shi azaman reagent don gano barasa na farko, na biyu, da na uku. Ana iya amfani da shi don haɗa magungunan bromoacetonitrile. A masana'antar magungunan kashe kwari, ana amfani da shi don haɗa thiabendazole kuma ana iya amfani da shi azaman mai kiyaye 'ya'yan itace, maganin kashe ƙwayoyin cuta, da wakili mai hana mildew, da sauransu. Yana da kayan haɗin halitta, wanda ake amfani da shi don daidaita halayen bromination mai ƙarancin kuzari, kuma ana amfani da shi wajen samar da ƙarin roba da magunguna. Ana iya amfani da shi don haɗa bromoacetonitrile don magani. A masana'antar magungunan kashe ƙwari, ana amfani da shi don haɗa thiabendazole kuma ana iya amfani da shi azaman mai kiyaye 'ya'yan itace, maganin kashe ƙwayoyin cuta, da wakili mai hana mildew. Ana amfani da shi azaman reagent don gano barasa na farko, na biyu, da na uku da ƙari ga samfuran roba, kuma ana amfani da shi azaman reagent don haɗa kwayoyin halitta. Yana da mahimmanci a cikin brominating a cikin haɗa kwayoyin halitta. A cikin masana'antar magunguna, galibi ana amfani da shi azaman brominating a cikin haɗa kwayoyin halitta, kamar haɗa cefaloram. Haɗa kwayoyin halitta. Haɗa kwayoyin halitta. Haɗa ethanol zuwa aldehydes da ketones. Haɗakar aldehydes zuwa bromo - acid. Wakili mai aiki da yawa na brominating. Ana amfani da shi a cikin amsawar oxidation na tryptophan, amma matakin oxidation na tyrosine, histidine, da methionine residents na iya zama ƙasa da haka. Haka kuma ana iya amfani da shi don gyara ƙungiyoyin ribosomal thiol. Wakili ne na brominating na duniya. A gaban AIBN, ana iya haɗa silyl ethers zuwa aldehydes. Yana da sinadarin brominating na duniya; ana amfani da shi don oxidation na tryptophan, kodayake akwai ragowar oxidation na tyrosine, histidine, da methionine zuwa ƙaramin mataki; ana amfani da shi don gyaran rukuni na ƙungiyoyin ribosomal thiol; a gaban AIBN, ana haɗa silyl ethers zuwa aldehydes.

Ajiyewa da adanawa

Rayuwar shiryayye: Watanni 24 daga ranar ƙera shi a cikin marufi na asali wanda ba a buɗe ba, an adana shi a wuri mai sanyi da bushewa, ba tare da hasken rana kai tsaye ba, ko ruwa.
Ma'ajiyar iska, Busar da ƙananan zafin jiki, An raba shi da sinadarai masu guba, acid.

Ya kamata a sanya iska a ma'ajiyar, a ajiye a ƙananan zafin jiki kuma a busar da ita. A adana ta daban da aniline, dialkyl sulfide, hydrazine hydrate, peroxides da propionitrile.
