Taw qhia
L-phenylalanine benzyl ester yog ib qho organic compound. Nws cov qauv tshuaj muaj L-aspartic acid molecule thiab benzyl esterified pawg.
L-Benzyl aspartate muaj daim ntawv dawb crystalline hmoov uas yog soluble hauv ethanol thiab chloroform ntawm chav tsev kub thiab me ntsis soluble hauv dej. Nws yog ib tug derivative nrog lub ntuj amino acid L-aspartic acid thiab plays ib tug tseem ceeb lom kev ua si nyob rau hauv cov kab mob nyob.
Txoj kev npaj L-benzyl aspartate yog hloov L-aspartic acid nrog benzyl cawv los ntawm esterification cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv feem ntau yog nqa tawm nyob rau hauv acidic tej yam kev mob thiab nrog rau kev siv ntawm tsim nyog acid catalysts.
Nws yog ib qho tshuaj thiab yuav tsum tau muab pov tseg raws li cov txheej txheem kev khiav hauj lwm thiab cov txheej txheem kev nyab xeeb. Tsis txhob kov cov tawv nqaij thiab qhov muag, thiab hnav hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv yog tias tsim nyog. Yog noj los yog nqus tau, nrhiav kev kho mob tam sim ntawd. Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo-ventilated, deb ntawm tshav kub thiab hluav taws.
