(S)-N-ALPHA-T-BUTYLOXYCARBONYL-PYROGLUTAMIC ACID T-BUTYL ESTER (CAS# 91229-91-3)

Okwu mmalite

di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate bụ ngwakọta nke usoro kemịkal ya bụ C14H23NO6. Nke a bụ nkọwa nke njirimara, ojiji, nkwadebe na ozi nchekwa nke ogige ahụ:

Ọdịdị:

-ọdịdị: di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate bụ enweghị agba na-acha ọcha crystalline siri ike.

-Solubility: Ọ bụ soluble na organic solvents dị ka ethanol, methanol na dimethyl sulfoxide.

- Ebe mgbaze: Ngwakọta ahụ na-agbaze na ihe dịka 104-105 ° C.

Jiri:

di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate bụ ihe a na-ejikarị amino acid eme ihe, nke a na-ejikarị dị ka reagent na njikọ organic. Enwere ike iji ya mepụta ogige ndị na-arụ ọrụ ndụ, dị ka ọgwụ na ihe polymer.

Usoro:

A na-eme nkwadebe nke di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate site na usoro ndị a:

1. Igbari pyroglutamic acid tert-butyl ester na akọrọ dimethyl sulfoxide.

2. A na-agbakwunye ego kwesịrị ekwesị nke N, N'-dihydroxyethyl isopropanamide ma mee ka ngwakọta mmeghachi omume dị jụụ n'okpuru 0 Celsius.

3. Tinye di-tert-butyl carbonate nwayọọ nwayọọ ka ị na-echekwa okpomọkụ nke ngwakọta mmeghachi omume n'okpuru 0 Celsius.

4. Mgbe emechara mmeghachi omume ahụ, a na-agbakwunye ngwakọta mmeghachi omume na mmiri iji mepụta ihe siri ike nke di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate.

5. E nwetara ngwaahịa ikpeazụ site na nzọụkwụ nke crystallization, filtration na ihicha.

Ozi nchekwa:

Di-tert-butyl (2S) -5-oxopyrrolidine-1,2-dicarboxylate kwesịrị iji ma jikwaa ya n'usoro dị mma iji zere ikpughe na akpụkpọ ahụ, anya na iku ume. Na mgbakwunye, a ga-echekwa ya n'ebe kpọrọ nkụ, dị jụụ ma pụọ ​​​​na ọkụ na oxidants. Maka ozi nchekwa akọwapụtara, rụtụ aka na Mpempe Data Safety Chemical (MSDS) ma ọ bụ ozi dabara adaba nke ndị na-ebubata ya nyere.
