Isicelo:

I-4-Nitro-L-Phenylalanine Hydrate (H-Phe(4-NO2)-OH∙H2O) (CAS: 949-99-5) isetshenziselwa ukuhlanganiswa kwe-peptide, uhlobo lokusabela: i-peptide synthesis yesigaba sesisombululo.Isetshenziswa njenge-organic synthesis ephakathi, emaphakathi yemithi, i-biochemical reagent noma i-chemical reagent.

Indlela yokulungiselela i-L-Phenylalanine 16.5g (mmol) yancibilika ku-50ml ka-85% H2SO4, yengezwa nge-dropwise kanye nokunyakaziswa ku-asidi exubile ye-hno3-concentrated H2SO4 (V/V:1.4/1.1) elungiselelwe ngaphambili futhi yapholiswa ekamelweni lokushisa ekamelweni. , futhi ukusabela kwashukunyiswa ekamelweni lokushisa kwe-5H, isixazululo sokusabela salungiswa ukuze sibe pH2-3 nge-40%I-NaOH ukukhiqiza inani elikhulu lemvula.I-precipitate yayihlungiwe, igezwe ngamanzi kuze kube yilapho ingathathi hlangothi, futhi yomiswa ngaphansi kwengcindezi encishisiweukuthola i-4-nitro-l-phenylalanine.
