Mawu Oyamba

Tert-butoxycarbonyl-D-alanine ndi organic pawiri. Ndi crystalline yoyera mpaka yopepuka yachikasu yomwe imasungunuka m'madzi ndi zosungunulira zokhala ndi mowa.

 

Njira yopangira tert-butoxycarbonyl-D-alanine nthawi zambiri imapangidwa ndi zomwe zimachitika. Njira yodziwika bwino ndikuchita tert-butoxycarbonyl chloroformic acid ndi D-alanine kupanga tert-butoxycarbonyl-D-alanine.

 

Chidziwitso cha Chitetezo: Tert-butoxycarbonyl-D-alanine nthawi zambiri imatha kuwonedwa ngati yotetezeka pakagwiritsidwe ntchito wamba. Monga mankhwala onse, kugwiritsa ntchito moyenera ndi kusunga ndikofunikira kwambiri. Kumeza, kupuma, kapena kukhudzana ndi khungu ndi maso kuyenera kupewedwa. Zida zodzitetezera monga magolovesi, zishango zakumaso, ndi zoteteza maso ziyenera kuvalidwa zikagwiritsidwa ntchito. Ngati mwakhudzana mwangozi kapena pokoka mpweya, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala mwamsanga. Pakusungirako, ziyenera kusungidwa pamalo owuma, ozizira, opanda mpweya wabwino, kutali ndi moto ndi zipangizo zoyaka. Malamulo am'deralo ndi njira zogwirira ntchito ziyenera kutsatiridwa.
