Intshayelelo
Yikhompawundi ephilayo ene-chemical formula C5H3BrFN2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: ayinambala ukuya kwikristale etyheli
-Indawo yokunyibilika: 110-113°C
-Indawo yokubila: 239°C (uxinzelelo lwe-atmospheric)
-Ubuninzi: 1.92g/cm³
-I-Soluble: I-Soluble kwi-ethanol, i-dimethylformamide kunye ne-acetonitrile
Sebenzisa:
-ihlala isetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis. Ingasetyenziselwa ukuhlanganiswa kweziyobisi, i-pesticides, idayi kunye noluhlu lwee-organic compounds.
-I-compound idlala indima ebalulekileyo kwintsimi yeyeza, njenge-synthesis yamachiza e-anticancer.
Indlela yokulungiselela:
-okanye inokufumaneka ngoluhlu lweempendulo ze-organic chemical synthesis. Indlela eqhelekileyo yokwenziwa kukukhusela, ukubhobhoza kunye ne-fluorination ye-pyrimidines. Indlela ethile yokudibanisa inokwenziwa ngokweemfuno zokwenyani.
Ulwazi ngoKhuseleko:
-Ingcaciso ethile yokhuseleko kufuneka imiselwe ngokweemeko ezithile zovavanyo kunye nokusetyenziswa.
-Xa usebenzisa i-compound, landela ngokungqongqo iinkqubo zokhuseleko lwebhubhoratri, kuquka ukugqoka izixhobo ezifanelekileyo zokukhusela, ukuphepha ukudibanisa nolusu kunye namehlo, kude nomlilo kunye nokushisa.
-Ukuvezwa ixesha elide kunye nokuphefumla kweli khompawundi kunokubangela ubungozi bempilo, ngoko ke kufuneka ubeke ingqalelo kumanyathelo okukhusela afanelekileyo kwaye ujongane nayo ngokuhambelana nendlela echanekileyo yovavanyo lwenkunkuma yovavanyo.
