Isicelo:

I-4-Nitro-L-Phenylalanine Hydrate (H-Phe (4-NO2) -OH∙H2O) (CAS: 949-99-5) isetyenziswe kwi-peptide synthesis, uhlobo lokuphendula: isisombululo se-peptide synthesis.Isetyenziswe njenge-organic synthesis ephakathi, i-pharmaceutical intermediate, i-biochemical reagent okanye i-reagent yekhemikhali.

Indlela yokulungiselela i-L-Phenylalanine 16.5g (mmol) yanyibilikiswa kwi-50ml ye-85% ye-H2SO4, yongezwa i-dropwise kunye nokuxutywa kwe-asidi edibeneyo ye-hno3-concentrated H2SO4 (V / V: 1.4 / 1.1) elungiselelwe kwangaphambili kwaye ipholile kwiqondo lobushushu begumbi. , kwaye i-reaction yavuselelwa kwiqondo lokushisa kwe-5H, isisombululo sokuphendula salungiswa kwi-pH2-3 kunye ne-40%NaOH ukuvelisa isixa esikhulu semvula.I-precipitate yahluzwa, ihlanjwe ngamanzi de ingathathi hlangothi, kwaye yomiswe phantsi koxinzelelo oluncitshisiweyoukufumana i-4-nitro-l-phenylalanine.
