Umgangatho

Idatha eqinisekisiweyo yeDatha eqinisekisiweyo

Le mveliso L-2-amino -3 (B-indole) propionic acid. Kubalwa njengemveliso eyomileyo, umxholo weC11H12N202 awuyi kuba ngaphantsi kwe-99.0%.

Iimpawu

Idatha eqinisekisiweyo yeDatha eqinisekisiweyo
  • Le mveliso imhlophe ukuya kwikristale etyheli okanye i-crystalline powder; Ayinavumba.
  • Le mveliso inyibilika kancinane emanzini, i-soluble kancinane kakhulu kwi-ethanol, ayinyibiliki kwi-chloroform, i-soluble kwi-formic acid; Ichithwe kwisisombululo sovavanyo lwe-sodium hydroxide okanye i-dilute i-hydrochloric acid.

ukujikeleza okuthe ngqo

thatha le mveliso, ukuchaneka ubunzima, yongeza amanzi ukunyibilika kunye quantitatively dilute ukwenza isisombululo equlathe malunga 10mg lml ​​nganye, kwaye ukugqiba ngokomthetho (umgaqo jikelele 0621), ujikelezo ethile -30.0 ° ukuya -32.5 °.

Intshayelelo

yi-isomer engeyondalo ye-tryptophan

Ukuxilongwa okwahlukileyo

Idatha eqinisekisiweyo yeDatha eqinisekisiweyo
  1. Izixa ezifanelekileyo zemveliso kunye nemveliso yereferensi ye-tryptophan yachithwa emanzini kwaye yaxutywa ukulungiselela isisombululo esiqulethe malunga ne-10mg nge-1 ml njengesisombululo sovavanyo kunye nesisombululo sereferensi. Ngokovavanyo lwemeko yechromatographic phantsi kwezinye i-amino acids, indawo kunye nombala wendawo ephambili yesisombululo sovavanyo kufuneka ifane neso sisombululo sereferensi.
  2. I-spectrum yokufunxa i-infrared yale mveliso kufuneka ihambelane naleyo yolawulo (i-Spectrum set 946).
  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
