H-Tyr-OEt·HCl CAS 4089-07-0 L-Tyrosine Ethyl Ester Hydrochloride Ma'ema'e >99.0% (HPLC) Hale Hana

Hoʻohana ʻia ʻo L-Tyrosine Ethyl Ester Hydrochloride (H-Tyr-OEt·HCl) (CAS: 4089-07-0) ma ke ʻano he lāʻau lapaʻau a me nā mea kūlohelohe a ma ke ʻano he mea pale amino koʻikoʻi.Hoʻohana ʻia ia e hoʻolauna i ka gene pale t-Boc.ʻO nā derivatives amino acids, hoʻohana ʻia i ka peptide synthesis, organic synthesis intermediates, pharmaceutical intermediates, biochemical reagents, chemical reagents.
Introduction: ʻO L-Tyrosine kekahi o nā ʻakika amino he 20 e hana ai i nā protein a he waikawa amino pono ia no nā mammals.ʻO L-Tyrosine Ethyl Ester Hydrochloride ka mea kumu nui no ka synthesis o nā ʻano hormones peptide, antibiotic a me nā lāʻau lapaʻau ʻē aʻe.
E hoʻohana: ʻO L-Tyrosine Ethyl Ester Hydrochloride ka mea kumu nui no ka synthesizing i nā ʻano hormones peptide, antibiotic a me nā lāʻau lapaʻau ʻē aʻe.I ka ʻoihana meaʻai, hoʻohana ʻia ʻo L-Tyrosine Ethyl Ester Hydrochloride ma kahi o nā waikawa amino e like me nā mea hoʻohui meaʻai, hiki ke hoʻololi i ka ʻono a me ka ʻono o ka meaʻai a hoʻonui i ke ola o ka meaʻai.ʻO nā esters amino acid i hoʻohana ʻia i ka meaʻai e hoʻonui i ka solubility o nā amino acids a me ka kikoʻī o ka enzyme catalysis, kahi mea e pono ai i ka digestion a me ka absorption o ke kino a ke pāʻani nei i ka hana ʻelua i ka meaʻai a me ka mālama olakino.
Kaʻina hoʻomākaukau: E hoʻohui i 19 mL o ka ethanol anhydrous i loko o ka pahu 3-waha 250 mL i hoʻolako ʻia me kahi mea hoʻoheheʻe, kahi pahu hoʻoheheʻe a me kahi thermometer, e hoʻomaha a hiki i -8 ℃ i loko o ka ʻauʻau paʻakai hau no ka hoʻohana ʻana i waho, e hoʻohui mālie i 2.4 mL o ʻO ka sulfoxide chloride ma lalo o ka hoʻoulu ʻana (ua kaupalena ʻia ka wikiwiki o ka hāʻule ʻana i ka mahana hopena ʻaʻole iʻoi aku ma mua o 0 ℃), ma hope o ka hāʻule ʻana, e hoʻoulu i kēia mahana no 1 h, e hoʻohui i 4.5g L-Tyrosine ma lalo o nā kūlana hoʻoluʻu, e hoʻokiʻekiʻe i ka mahana i ka lumi wela a hoʻoulu. 2 h, a laila wela a me ka reflux ma 65 ℃ no 2 h, hoʻomaʻemaʻe ma hope o ka hopena e hoʻoheheʻe i ka hapa nui o ka methanol a me ka thionyl chloride, e hoʻoneʻe i ke koena i ka beaker no ka hoʻomaha ʻana, e hoʻohui i 125 mL ethyl acetate e hoʻoheheʻe i ka nui o nā crystals, vacuum. kānana, a hōʻiliʻili i nā kristal, ua loaʻa iā L-Tyrosine Ethyl Ester Hydrochloride.
