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

Fa'aaogāga

O le N-Bromosuccinimide, e masani ona faapuupuuina o le NBS, o se mea manifinifi e lanu paʻepaʻe pe paʻepaʻe. E mafai ona solo i le acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, ma le acetonitrile, e faigofie ona solo i le vai ma le acetic acid, ma e le solo i le ether, hexane, ma le carbon tetrachloride. E masani ona faʻaaogaina le NBS i le free radical bromination reactions o allyl ma benzyl groups; electrophilic bromination reactions o ketones, aromatic compounds, poʻo heterocyclic compounds; hydroxylation, etherification, ma lactonization reactions o olefins. E maaleale le NBS i le susu ma e tatau ona teuina i totonu o se pusaaisa. I le taimi o le faʻaaogaina, e tatau ona ʻalofia le manavaina pe paʻi atu i le paʻu, ma e masani ona faʻagaoioia i totonu o se fume hood ma le lelei o le ea.

Fa'aaogaina o se vaila'au mo le fa'ailoaina o ava malosi muamua, lona lua, ma lona tolu. E mafai ona fa'aaogaina e fa'aputu ai vaila'au bromoacetonitrile. I le alamanuia o vaila'au fa'asaina, e fa'aaogaina e fa'aputu ai le thiabendazole ma e mafai fo'i ona fa'aaogaina o se mea e fa'asao ai fuala'au 'aina, vaila'au fa'amamā, ma vaila'au e tete'e atu i le mildew, ma isi mea fa'apena. O se mea mata e fa'aputu ai mea fa'aola, e fa'aaogaina e fa'atonutonu ai tali atu i le bromination e maualalo le malosi, ma e fa'aaogaina fo'i i le gaosiga o mea fa'aopoopo pa'u ma vaila'au. E mafai ona fa'aaogaina e fa'aputu ai le bromoacetonitrile mo vaila'au. I le alamanuia o vaila'au fa'asaina, e fa'aaogaina e fa'aputu ai le thiabendazole ma e mafai fo'i ona fa'aaogaina o se mea e fa'asao ai fuala'au 'aina, vaila'au fa'amamā, ma vaila'au e tete'e atu i le mildew. Fa'aaogaina o se vaila'au mo le fa'ailoaina o ava malosi muamua, lona lua, ma lona tolu ma se mea fa'aopoopo mo oloa pa'u, ma e fa'aaogaina fo'i i le fa'aputuga mea fa'aola. O se vaila'au taua e fa'aputu ai mea fa'aola i le fa'aputuga mea fa'aola. I le alamanuia o vaila'au, e masani ona fa'aaogaina o se vaila'au e fa'aputu ai mea fa'ama'i, e pei o le fa'aputuga o cefaloram. Fa'aputuga mea fa'aola. Bromination o olefins. Oxidation o le ethanol i aldehydes ma ketones. Okesene o aldehydes i bromo - acids. Mea e tele galuega e fa'aaoga mo le brominating. E fa'aaogaina i le tali atu o le oxidation o le tryptophan, ae o le tikeri o le oxidation o le tyrosine, histidine, ma methionine residues e ono maualalo. E mafai foi ona fa'aaogaina mo le suia o vaega ribosomal thiol. O se mea e fa'aaoga mo le brominating. I le i ai o le AIBN, e mafai ona fa'aaoga mo le silyl ethers i aldehydes. O se mea e fa'aaoga mo le brominating; e fa'aaogaina mo le oxidation o le tryptophan, e ui lava atonu e iai tyrosine, histidine, ma methionine oxidation residues i se tulaga maualalo; e fa'aaogaina mo le suia o vaega o vaega ribosomal thiol; i le i ai o le AIBN, e fa'aaoga mo le silyl ethers i aldehydes.

Afifiina ma le Felauaiga

25KG/Palu po'o mana'oga o tagata fa'atau.
E patino i oloa masani ma e mafai ona tilivaina i le vasa ma le ea

Tausia ma teuina

Umi e teu ai: 24 masina mai le aso na gaosia ai i totonu o le afifiina muamua e leʻi tatalaina teuina i se nofoaga malūlū ma mago, ʻaloʻese mai le la saʻo, vai.
Faleteuoloa e fa'amamago i le ea, fa'amago i le vevela maualalo, Vavae'ese mai mea e fa'aola ai le ea, 'asi.

E tatau ona fa'amamago lelei le faleteuoloa, ia fa'aitiitia le vevela ma ia mago. Teu 'ese mai le aniline, dialkyl sulfide, hydrazine hydrate, peroxides ma le propionitrile.
