(S)-N-ALPHA-T-BUTYLOXYCARBONYL-PYROGLUTAMIC ACID T-BUTYL ESTER (CAS# 91229-91-3)
Hordhac
di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate waa iskudhis ay qaaciido kiimikaad tahay C14H23NO6. Kuwa soo socda waa sharaxaadda guryaha, isticmaalkooda, diyaarinta iyo macluumaadka badbaadada xarunta:
Dabeecadda:
-Muuqaalka: di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate waa crystalline cad oo aan midab lahayn.
-Solubility: Waxay ku milmaysaa dareerayaasha organic sida ethanol, methanol iyo dimethyl sulfoxide.
-Meelting point: Iskudhisku wuxuu dhalaaliya qiyaastii 104-105 ° C.
Isticmaal:
di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate waa amino acid derivative caadi ahaan loo isticmaalo, oo inta badan loo isticmaalo sidii reagen ah in synthesis organic. Waxaa loo isticmaali karaa in lagu soo saaro xeryahooda bayooloji ahaan firfircoon, sida daawooyinka iyo walxaha polymer.
Habka:
Diyaarinta di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate waxaa badanaa lagu fuliyaa tallaabooyinka soo socda:
1. Ku milmi pyroglutamic acid tert-butyl ester dimethyl sulfoxide qalalan.
2. Qadar habboon oo N,N'-dihydroxyethyl isopropanamide ah ayaa lagu daray waxaana isku darka falcelinta lagu qaboojiyey meel ka hooseysa 0°C.
3. Si tartiib ah ugu dar di-tert-butyl carbonate iyadoo la ilaalinayo heerkulka isku dhafka falcelinta ka hooseeya 0°C.
4. Ka dib marka la dhammeeyo falcelinta, isku darka falcelinta ayaa lagu daray biyaha si loo soo saaro roob adag oo di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate.
5. Badeecada kama dambaysta ah waxaa lagu helay tallaabooyinka crystallization, sifeynta iyo qalajinta.
Macluumaadka Badbaadada:
di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate waa in la isticmaalo oo loo maareeyaa si waafaqsan dhaqamada badbaadada leh si looga fogaado soo-gaadhista maqaarka, indhaha iyo neefsashada. Intaa waxaa dheer, waa in lagu kaydiyaa meel qalalan, qabow oo ka fog dabka iyo oksidayaasha. Macluumaad gaar ah oo badbaado leh, tixraac Xaashida Badbaadada Kiimikada (MSDS) ama macluumaadka khuseeya ee uu bixiyay alaab-qeybiyaha.
