N-alpha-(tert-Butoxycarbonyl)-L-lysine (CAS# 13734-28-6) intshayelelo
I-N-Boc-L-lysine yi-amino acid derivative equlethe iqela elikhuselayo i-Boc (t-butoxycarbonyl) kwisakhiwo sayo. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela, kunye nolwazi lokhuseleko lwe-N-Boc-L-lysine:
indalo:
-Inkangeleko: Imhlophe okanye ivaliwe i-crystalline powder emhlophe
-I-Solubility: Inyibilika kwizinyibilikisi eziqhelekileyo ze-organic ezifana ne-methanol, i-ethanol, kunye ne-dichloromethane.
Injongo:
-Inokusebenza njengeqela elikhuselayo le-L-lysine, ukukhusela amaqela ayo e-amino okanye i-carboxyl phantsi kweemeko ezithile zokusabela ukuthintela ukusabela okungeyomfuneko ukuba kwenzeke.
Indlela yokuvelisa:
-I-synthesis ye-N-Boc-L-lysine ifumaneka ikakhulu ngokusabela kweqela elikhuselayo le-L-lysine. Indlela yokulungiselela eqhelekileyo kukuqala ukuphendula i-L-lysine kunye ne-Boc2O (t-butoxycarbonyl dicarboxylic anhydride) okanye i-Boc-ONH4 (t-butoxycarbonyl hydroxylamine hydrochloride) ukwenza i-N-Boc-L-lysine kunye neqela elikhuselayo le-Boc.
Ulwazi lokhuseleko:
-N-Boc-L-lysine yikhemikhali, kwaye kufuneka kuthathwe amanyathelo okhuseleko xa uyisebenzisa, kunye nezikhokelo ezifanelekileyo zokhuseleko kufuneka zilandelwe.
-Inokucaphukisa ulusu, amehlo, kunye nenkqubo yokuphefumula, kwaye kufuneka ihlanjululwe ngokukhawuleza ngamanzi amaninzi emva koqhagamshelwano.
-Xa uphatha kunye nokugcina, thintela ukudibanisa ne-oxidants, iziseko ezinamandla, kunye ne-acids, ugweme ukugcinwa kwezinto ezinkulu, kwaye ugweme ukushisa okuphezulu kunye nemithombo yomlilo.
-Nceda uphathe kwaye ulahle iikhemikhali ezingafunwayo okanye eziphelelwe lixesha ngendlela echanekileyo ukunciphisa umngcipheko wokungcoliseka kwendalo.
