H-Tyr-OEt·HCl CAS 4089-07-0 L-Tyrosine Ethyl Ester Hydrochloride Purity >99.0% (HPLC) Falegaosimea

L-Tyrosine Ethyl Ester Hydrochloride (H-Tyr-OEt·HCl) (CAS: 4089-07-0) o loʻo faʻaaogaina e avea o se fomaʻi ma vailaʻau faʻapitoa ma o se vailaʻau puipuia amino taua.E faʻaaogaina foi e faʻafeiloaʻi ai le t-Boc protect gene.Amino acids derivatives, faʻaaogaina i le peptide synthesis, organic synthesis intermediates, pharmaceutical intermediates, biochemical reagents, chemical reagents.
Folasaga: L-Tyrosine o se tasi o le 20 amino acids e fausia ai polotini ma o se amino acid taua mo mamame.L-Tyrosine Ethyl Ester Hydrochloride o le mea autu autu mo le tuʻufaʻatasia o le tele o hormones peptide, vailaʻau faʻamaʻi ma isi vailaʻau.
Fa'aoga: L-Tyrosine Ethyl Ester Hydrochloride o le mea autu autu mo le faʻapipiʻiina o hormones peptide eseese, vailaʻau faʻamaʻi ma isi vailaʻau.I totonu o pisinisi taumafa, L-Tyrosine Ethyl Ester Hydrochloride o loʻo faʻaaogaina nai lo amino acids e fai ma meaʻai faaopoopo, lea e mafai ona suia ai le tofo ma le tofo o meaʻai ma faʻateleina ai le ola o meaʻai.Amino acid esters o loʻo faʻaaogaina i meaʻai e faʻateleina ai foʻi le solubility o amino acids ma le faʻapitoa o le enzyme catalysis, lea e aoga i le gaogao ma le faʻaogaina o le tino ma e taʻalo se vaega lua i meaʻai ma le soifua maloloina.
Sauniuniga auala: Faaopopo le 19 mL o le ethanol anhydrous i totonu o le 250 mL tolu-gutu fagu o loʻo faʻapipiʻiina i se faʻafefete, se faʻafefe faʻafefe ma se vevela, faʻamalie i le tusa o le -8 ℃ i totonu o se taele masima aisa mo le faʻaogaina i fafo, faʻaopoopo malie le 2.4 mL o sulfoxide chloride i lalo o le faʻafefeteina (o le pa'ū faʻavavevave e faʻatapulaʻa i le vevela o le tali e le sili atu i le 0 ℃), a maeʻa ona paʻu, faʻafefe i lenei vevela mo le 1 h, faʻaopopo le 4.5g L-Tyrosine i lalo o le malulu, siitia le vevela i le potu vevela ma faʻaoso mo 2 h, ona vevela ma reflux i le 65 ℃ mo le 2 itula, faʻamalo pe a maeʻa le tali e faʻafefe ai le tele o le methanol ma le sili atu o le thionyl chloride, faʻafeiloaʻi le toega i se fagu mo le malulu, faʻaopoopo le 125 mL ethyl acetate e faʻafefe ai se aofaiga tele o tioata, vacuum filtration, ma aoina tioata, L-Tyrosine Ethyl Ester Hydrochloride na maua.
