ʻO Tert-butoxycarbonyl-D-alanine kahi mea hoʻohuihui. He paʻa keʻokeʻo a ʻulaʻula melemele ʻeleʻele i hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe waiʻona.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana o tert-butoxycarbonyl-D-alanine ka mea maʻamau e synthesized e ka hopena. ʻO ke ala maʻamau ka hana ʻana i ka tert-butoxycarbonyl chloroformic acid me D-alanine e hana i ka tert-butoxycarbonyl-D-alanine.

 

ʻIke palekana: ʻO Tert-butoxycarbonyl-D-alanine hiki ke noʻonoʻo ʻia he palekana ma lalo o nā kūlana hoʻohana maʻamau. E like me nā kemika a pau, he mea nui ka hoʻohana pono ʻana a me ka mālama ʻana. Pono e ʻalo ʻia ka ʻai ʻana, ka hanu ʻana, a i ʻole ka pili ʻana me ka ʻili a me nā maka. Pono e hoʻohana ʻia nā mea pale e like me nā mīkina lima, nā pale maka, a me nā maka pale i ka wā e hoʻohana ai. Inā loaʻa ka pilikia a i ʻole ka inhalation, holoi koke me ka wai nui a ʻimi koke i ka lāʻau lapaʻau. I ka wā o ka mālama ʻana, pono e mālama ʻia i kahi maloʻo, ʻoluʻolu, maikaʻi-ventilated, ma kahi mamao o ke ahi a me nā mea hiki ke ahi. Pono e mālama ʻia nā kānāwai kūloko a me nā kaʻina hana.
