Cov Ntawv Thov
1. Chiral Resolution Tus Neeg Sawv Cev
Feem ntau siv los daws teeb meem kho cov amines lossis alkaloids ntawm diastereomic ntsev tsim.
Muab cov enantiomer siab ntau dhau thaum sib cais chiral bases (piv txwv li, cov chaw muag khoom siv).
2. Derivatization reagent hauv HPLC
Reacts nrog Rapemic Mixttures los tsim cov diastereomers txawv ntawm chiral HPLC lossis NMR.
Tshwj xeeb yog muaj txiaj ntsig rau kev txheeb xyuas:
Cov amino acids
Alkaloids
-Obroters
Lwm qhov yooj yim sib xyaw
3. Khoom cua ntawm chiral ligands lossis catalysts
Ua hauj lwm ua chiral lub tsev thaiv hauv cov synthesis thiab kev sib koom ua ke chemistry.
Cov txiaj ntsig
Kev xaiv siab rau kev daws teeb meem ntawm chiral bases
Tau tshaj tawm ntau yam ntawm cov kuab tshuaj organic
Ruaj khov thiab yooj yim rau kov cov khoom ntim
Enantiomerically refeugent ua kom ntseeg tau cov kev ntxub ntxaug chairal kev ntxub ntxaug
Tag
(+) - Di-1,4-toluoyl-d-tartaric acid (CASS 4634-68-7) yog qhov ua tau zoo chiral daws teeb meem organic, thiab kev ntsuas tshuaj. Nws qhov kev lees paub chariral tau ua rau nws tsis tseem ceeb rau kev daws teeb meem thiab txheeb xyuas cov chaw ua haujlwm ua ke.
Cim npe nrov: (+) - Di-1,4-toluoyl-d-tartaric acid 丨 32634-68-7, Tuam Tshoj (+) (+))
