L-Tyrosine Ethyl Ester Hydrochloride (H-Tyr-OEt·HCl) (CAS: 4089-07-0) na-eji dị ka a ọgwụ na organic etiti na dị ka ihe dị mkpa na-echebe amino.A na-ejikwa ya ewebata mkpụrụ ndụ ihe nchebe t-Boc.Ihe mmepụta amino acids, nke a na-eji na peptide synthesis, organic synthesis intermediates, pharmaceutical intermediates, biochemical reagents, chemical reagents.
Okwu mmalite: L-Tyrosine bụ otu n'ime amino asịd iri abụọ mebere protein ma bụrụkwa amino acid dị mkpa maka ụmụ anụmanụ.L-Tyrosine Ethyl Ester Hydrochloride bụ isi akụrụngwa maka njikọ nke homonụ peptide dị iche iche, ọgwụ nje na ọgwụ ndị ọzọ.
Jiri: L-Tyrosine Ethyl Ester Hydrochloride bụ isi akụrụngwa maka imepụta ụdị homonụ peptide dị iche iche, ọgwụ nje na ọgwụ ndị ọzọ.N'ụlọ ọrụ nri, a na-eji L-Tyrosine Ethyl Ester Hydrochloride kama amino acid dị ka ihe mgbakwunye nri, nke nwere ike ịgbanwe uto na ụtọ nri ma nwekwuo ndụ nchekwa.Amino acid esters eji na nri na-abawanye solubility nke amino asịd na kpọmkwem nke enzyme catalysis, nke bara uru na mgbaze na absorption nke ahụ na-arụ a dual ọrụ na oriri na ọṅụṅụ na ahụ ike.
Usoro nkwadebe: Tinye 19 mL nke ethanol anhydrous n'ime 250 mL flask atọ nke nwere ihe mkpali, oghere na-adaba na temometa, mee ka ọ dị jụụ ruo ihe dị ka -8 ℃ n'ime mmiri ịsa mmiri nnu maka iji mpụga, jiri nwayọọ nwayọọ tinye 2.4 ml. sulfoxide chloride n'okpuru mkpali (ntọhapụ osooso na-ejedebeghị na mmeghachi omume okpomọkụ na-erughị 0 ℃), mgbe idobe, kpalie na a okpomọkụ maka 1 h, tinye 4.5g L-Tyrosine n'okpuru jụrụ ọnọdụ, welie okpomọkụ na ụlọ okpomọkụ ma kpalie maka. 2 h, wee kpoo ọkụ na reflux na 65 ℃ maka 2 h, distill mgbe mmeghachi omume na-ekpochapụ ọtụtụ methanol na ngafe thionyl chloride, nyefee ihe fọdụrụ na beaker maka jụrụ oyi, tinye 125 ml ethyl acetate na-ebuli nnukwu kristal, oghere. nzacha, na ịnakọta kristal, enwetara L-Tyrosine Ethyl Ester Hydrochloride.
