Intshayelelo

I-Tert-butoxycarbonyl-D-alanine yikhompawundi ephilayo. Yikristale eqinileyo emhlophe ukuya kwetyheli enyibilikayo emanzini nakwizinyibilikisi ezisekwe etywaleni.

 

Indlela yokulungiselela i-tert-butoxycarbonyl-D-alanine ngokuqhelekileyo yenziwa ngokusabela. Indlela eqhelekileyo kukusabela i-tert-butoxycarbonyl chloroformic acid kunye ne-D-alanine ukuvelisa i-tert-butoxycarbonyl-D-alanine.

 

Ulwazi ngoKhuseleko: I-Tert-butoxycarbonyl-D-alanine ingathathwa njengekhuselekile ngokubanzi phantsi kweemeko zokusetyenziswa kwesiqhelo. Njengazo zonke iikhemikhali, ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kubaluleke kakhulu. Ukuginya, ukuphefumla, okanye ukudibana nolusu namehlo kufuneka kuphetshwe. Izixhobo zokukhusela ezifana neeglavu, izikhuselo zobuso, kunye nempahla yamehlo ekhuselayo kufuneka zinxitywe xa zisetyenziswa. Kwimeko yokudibanisa ngengozi okanye ukuphefumla, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango ngokukhawuleza. Ngexesha lokugcinwa, kufuneka ligcinwe kwindawo eyomileyo, epholileyo, enomoya, kude nomlilo kunye nezinto ezinokutsha. Imimiselo yendawo kunye neenkqubo zokusebenza kufuneka zilandelwe.
