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

Hoʻohana

ʻO N-Bromosuccinimide, i hoʻopōkole pinepine ʻia ʻo NBS, he mea crystalline maikaʻi loa ia he keʻokeʻo a keʻokeʻo paha ke kala. Hiki ke hoʻoheheʻe ʻia i loko o ka acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, a me ka acetonitrile, hoʻoheheʻe iki ʻia i ka wai a me ka waikawa acetic, a ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka ether, hexane, a me ke kalapona tetrachloride. Hoʻohana pinepine ʻia ʻo NBS i nā hopena bromination radical manuahi o nā hui allyl a me benzyl; nā hopena bromination electrophilic o nā ketones, nā hui aromatic, a i ʻole nā ​​​​hui heterocyclic; nā hopena hydroxylation, etherification, a me lactonization o nā olefins. He maʻalahi ka NBS i ka makū a pono e mālama ʻia i loko o ka friji. I ka wā o ke kaʻina hana hoʻohana, pono e pale ʻia ka hanu ʻana a i ʻole ka pili ʻana me ka ʻili, a hana pinepine ʻia ia i loko o kahi uhi fume me ka hana ea maikaʻi.

Hoʻohana ʻia ma ke ʻano he reagent no ka ʻike ʻana i nā waiʻona mua, lua, a me ke kolu. Hiki ke hoʻohana ʻia e synthesize i nā lāʻau bromoacetonitrile. I ka ʻoihana pesticide, hoʻohana ʻia e synthesize i ka thiabendazole a hiki ke hoʻohana ʻia ma ke ʻano he mea mālama hua, antiseptic, a me ka mildew-proof agent, etc. He mea maka synthesis organik ia, i hoʻohana ʻia e hoʻoponopono i nā hopena bromination haʻahaʻa-ikehu, a hoʻohana ʻia hoʻi i ka hana ʻana o nā mea hoʻohui rubber a me nā lāʻau lapaʻau. Hiki ke hoʻohana ʻia e synthesize i ka bromoacetonitrile no ka lāʻau lapaʻau. I ka ʻoihana pesticide, hoʻohana ʻia e synthesize i ka thiabendazole a hiki ke hoʻohana ʻia ma ke ʻano he mea mālama hua, antiseptic, a me ka mildew-proof agent. Hoʻohana ʻia ma ke ʻano he reagent no ka ʻike ʻana i nā waiʻona mua, lua, a me ke kolu a me kahi mea hoʻohui no nā huahana rubber, a hoʻohana ʻia hoʻi i ka synthesis organik. He mea brominating koʻikoʻi ia i ka synthesis organik. I ka ʻoihana lāʻau lapaʻau, hoʻohana pinepine ʻia ma ke ʻano he mea brominating i ka synthesis o nā antibiotics, e like me ka synthesis o cefaloram. synthesis organik. Bromination o nā olefins. Oxidation o ka ethanol i aldehydes a me ketones. ʻO ka oxidation o nā aldehydes i nā waikawa bromo. Mea hoʻolaha brominating multi-functional. Hoʻohana ʻia ia i ka hopena oxidation o ka tryptophan, akā ʻo ke kekelē oxidation o nā tyrosine, histidine, a me nā koena methionine he haʻahaʻa paha. Hiki ke hoʻohana ʻia no ka hoʻololi ʻana i nā hui ribosomal thiol. He mea hoʻolaha brominating honua ia. I ke alo o AIBN, hiki ke oxidized ʻia nā silyl ethers i aldehydes. He mea hoʻolaha brominating honua ia; hoʻohana ʻia no ka oxidation o ka tryptophan, ʻoiai aia paha he tyrosine, histidine, a me nā koena oxidation methionine i kahi liʻiliʻi; hoʻohana ʻia no ka hoʻololi ʻana o ka hui o nā hui ribosomal thiol; i ke alo o AIBN, ua oxidized ʻia nā silyl ethers i aldehydes.

ʻŌpala a me ka Hoʻouna ʻana

25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa

Mālama a me ka mālama ʻana

Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.

Pono e hoʻomehana ʻia ka hale kūʻai, e mālama ʻia ma ka mahana haʻahaʻa a maloʻo. E mālama kaʻawale mai ka aniline, dialkyl sulfide, hydrazine hydrate, peroxides a me propionitrile.
