(S)-N-ALPHA-T-BUTYLOXYCARBONYL-PYROGLUTAMIC ACID T-BUTYL ESTER（CAS# 91229-91-3)
Nhanganyaya
di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate isanganiswa ine chimiro chemakemikari iC14H23NO6. Iyi inotevera tsananguro yezvivakwa, mashandisiro, kugadzirira uye kuchengetedza ruzivo rwekomboni:
Zvakasikwa:
-Kuonekwa: di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate is colorless to white crystalline solid.
-Solubility: Inonyungudika mune organic solvents senge ethanol, methanol uye dimethyl sulfoxide.
-Kunyungudika: Mushonga unonyunguduka panenge pa104-105°C.
Shandisa:
di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate inowanzoshandiswa amino acid derivative, inowanzoshandiswa se reagent mu organic synthesis. Inogona kushandiswa kugadzira biologically inoshanda makomisheni, akadai semishonga uye polymer zvinhu.
Nzira:
Kugadzirira kwe di-tert-butyl (2S)-5-oxopyrrolidine-1,2-dicarboxylate inowanzoitwa nematanho anotevera:
1. Dissolve pyroglutamic acid tert-butyl ester mune yakaoma dimethyl sulfoxide.
2. Nhamba yakakodzera yeN, N'-dihydroxyethyl isopropanamide yakawedzerwa uye musanganiswa wekuita wakatonhodzwa kusvika pasi pe0°C.
3. Wedzera di-tert-butyl carbonate zvishoma nezvishoma uchichengetedza tembiricha yemusanganiswa wekuita iri pasi pe0°C.
4. Mushure mekupedzwa kwekuita, musanganiswa wekuita wakawedzerwa kumvura kuti ibudise mvura yakasimba ye di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate.
5. Chigadzirwa chekupedzisira chakawanikwa nematanho e-crystallization, filtration uye kuomeswa.
Zvekuchengetedza
di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate inofanira kushandiswa uye kubatwa maererano nemaitiro akachengeteka kudzivirira kutarisana neganda, maziso uye inhalation. Mukuwedzera, inofanira kuchengetwa munzvimbo yakaoma, inotonhorera uye kure nemoto uye oxidants. Kuti uwane ruzivo rwakakwana rwekuchengetedza, tarisa kuChemical Safety Data Sheet (MSDS) kana ruzivo rwakakodzera rwunopihwa nemutengesi.
