Intshayelelo
I-5-Bromo-2,3-diaminopyridine yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
- Ukubonakala: I-5-Bromo-2,3-diaminopyridine imhlophe ukuya kwikristale ekhanyayo ephuzi okanye i-crystalline powder.
- Ukunyibilika: Ikhompawundi iyanyibilika kancinane emanzini kwaye inonyibiliko olulungileyo kwizinyibilikisi zendalo.
Sebenzisa:
- I-5-Bromo-2,3-diaminopyridine isetyenziswa ngokuqhelekileyo njenge-reagent kwiimpendulo ze-organic synthesis.
- Ingasetyenziselwa njengendawo ephakathi kwi-synthesis ye-coordination compounds okanye i-catalysts.
Indlela:
Ukulungiswa kwe-5-bromo-2,3-diaminopyridine kunokufezekiswa ngala manyathelo alandelayo:
1. Dissolve 2,3-diaminopyridine in dilute hydrochloric acid kuqala.
2. I-sodium nitrite iye yongezwa ukwenza iikhompawundi ze-nitroso.
3. Ngaphantsi kweemeko zokuhlambela kwamanzi e-ice, i-potassium bromide yongezwa kwifom ye-5-bromo-2,3-diaminopyridine.
Ulwazi ngoKhuseleko:
- I-5-Bromo-2,3-diaminopyridine i-organic compound kufuneka igcinwe kwaye isetyenziswe ngokufanelekileyo ukuphepha ukudibanisa nolusu kunye namehlo.
- Xa usebenza, kufuneka kuthathwe amanyathelo afanelekileyo okhuseleko aselebhu, njengokunxiba izixhobo ezifanelekileyo zokukhusela (umzekelo, iiglavu, iiglasi, idyasi yelebhu, njl. njl.).
- Bamba ikhompawundi ngendlela yokuphepha naziphi na iingozi ezibangelwa kukuphefumla, ukuginya, okanye ukudibana.
Kuphando lweekhemikhali kunye novavanyo, kubalulekile ukwenza umsebenzi olungileyo wolawulo lokhuseleko lwebhubhoratri kwaye usebenze ngokwesikhokelo seengcali.
