N-Boc-L-lysine ke derivative ea amino acid e nang le sehlopha se sireletsang Boc (t-butoxycarbonyl) sebopeho sa eona. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa, le tlhaiso-leseling ea polokeho ea N-Boc-L-lysine:

tlhaho:
-Ponahalo: phofo e tšoeu ea kristale kapa e tšoeu
-Solubility: E qhibiliha ka har'a metsoako e tloaelehileng ea tlhaho e kang methanol, ethanol le dichloromethane.

Morero:
-E ka sebetsa e le sehlopha se sireletsang L-lysine, se sireletsang lihlopha tsa eona tsa amino kapa carboxyl tlas'a maemo a itseng a karabelo ho thibela liketso tse sa hlokahaleng hore li se ke tsa etsahala.

Mokhoa oa tlhahiso:
-The synthesis ea N-Boc-L-lysine e fumaneha haholo-holo ka karabelo ea sehlopha se sireletsang sa L-lysine. Mokhoa o tloaelehileng oa ho itokisa ke ho qala ka ho itšoara ka L-lysine le Boc2O (t-butoxycarbonyl dicarboxylic anhydride) kapa Boc-ONH4 (t-butoxycarbonyl hydroxylamine hydrochloride) ho theha N-Boc-L-lysine le sehlopha se sireletsang sa Boc.

Lintlha tsa ts'ireletso:
-N-Boc-L-lysine ke k'hemik'hale, 'me mehato ea tšireletso e lokela ho nkoa ha u e sebelisa,' me ho lokela ho lateloa tataiso e nepahetseng ea tšireletso.
-E ka 'na ea halefisa letlalo, mahlo, le tsamaiso ea ho hema,' me e lokela ho hlatsoa hang-hang ka metsi a mangata ka mor'a ho kopana.
-Ha u tšoara le ho boloka, qoba ho kopana le li-oxidants, li-bases tse matla, le li-acids, qoba polokelo e kholo, 'me u qobe mocheso o phahameng le mehloli ea mollo.
-Ka kopo tšoara le ho lahla lik'hemik'hale tse sa batleheng kapa tse felileng ka mokhoa o nepahetseng ho fokotsa kotsi ea tšilafalo ea tikoloho.
