5-BROMO-2-HYDROXY-4-METHYLPYRIDINE (CAS# 164513-38-6) Intshayelelo

Yikhompawundi ye-organic kunye ne-chemical formula C8H8BrNO. Inezi mpawu zilandelayo:1. Imbonakalo: Yinto eqinileyo engenambala okanye etyheli ekhanyayo.2. Ukunyibilika: Inokunyibilika ngokuyinxenye emanzini kwaye kulula ukunyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-dimethyl sulfoxide.

3. Ixabiso le-PH: Ayithathi hlangothi okanye i-acidic kancinane kwisisombululo esimanzi.

4. I-Reactivity: Yi-reagent ye-electrophilic enokuthi ithathe inxaxheba kwiimpendulo ezininzi zezinto eziphilayo, ezifana ne-electrophilic substitution reactions, i-oxidation reactions, njl.

5. Ukuzinza: Izinzile kwiqondo lokushisa, kodwa inokubola phantsi kwesenzo sokushisa okuphezulu, i-oxidant okanye i-asidi eqinile.

Inoluhlu olubanzi lwezicelo kwilabhoratri nakwishishini, kubandakanya oku kulandelayo:

1. Njenge-reagent yekhemikhali: ingasetyenziselwa njenge-electrophilic reagent, i-Catalyst okanye i-agent yokunciphisa kwi-organic synthesis.

2. Njengesithinteli: Ngenxa yeempawu zayo zokulwa ne-antibacterial, ingasetyenziselwa ukulungiswa kwezinto zokukhusela, ezihlala zisetyenziselwa ukukhusela iinkuni, iingubo, njl.

3. Inkalo yezoNyango: ingasetyenziswa ekudityanisweni kweziyobisi okanye njengeziphakathi kumachiza athile.

Indlela eqhelekileyo yokulungiselela ityuwa kukuphendula i-2-picoline nge-bromine. Amanyathelo athile angabhekisela kule ndlela ilandelayo: Okokuqala, phantsi kweemeko ezifanelekileyo zokuphendula, i-2-methylpyridine iphendulwa nge-bromine ukufumana i-5-bromo-2-methylpyridine. Emva koko, phantsi kweemeko ze-alkaline, i-5-bromo -2-methyl pyridine iphathwa nge-sodium hydroxide ukufumana.

Ngokuphathelele ulwazi lokhuseleko, oku kulandelayo kufuneka kuqatshelwe xa usebenzisa okanye uphethe isinyithi:

1. Kulumkele ukudibana ngqo nolusu, amehlo, inkqubo yokuphefumla, njl.njl. Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi kunye nemaski.

2. Gcina indawo enomoya omhle ngexesha lokusetyenziswa kwaye ugweme ukuphefumla umphunga wayo.

3. Ukugcinwa kufuneka kufakwe kwisitya esivaliweyo, ugweme ukukhanya kwelanga kunye nokushisa okuphezulu.

4. Ukuba uginywe ngengozi okanye ukudibana kwesikhumba kwenzeka, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango ngexesha.

5. Ekusetyenzisweni okanye ukulahlwa kwekhompawundi, kufuneka ihambelane nemithetho yendawo kunye nemigaqo kunye neenkqubo zokhuseleko.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
