Isingeniso
(S)-2-(1-Hydroxyethyl)pyridine iyinhlanganisela ye-chiral enefomula yamakhemikhali engu-C7H9NO futhi inezici zokubona. Inama-stereoisomer amabili, okuyi-(S)-2-(1-Hydroxyethyl)pyridine eyodwa. Iwuketshezi olungenambala ukuya kokuphuzi olunephunga elingavamile.
(S)-2-(1-Hydroxyethyl)pyridine ivamise ukusetshenziswa njenge-chiral inducer noma i-catalyst ku-organic synthesis. Ingasetshenziswa ekuhlanganiseni ezinye izinhlanganisela ze-stereoisomer, ama-catalysts wokusabela kwe-organic synthesis, ukuhlanganiswa kwezidakamizwa oku-oda okuphezulu nokunye.
Ukulungiswa kwe-(S)-2-(1-Hydroxyethyl)pyridine ngokuvamile kutholakala ngokuphendula i-pyridine nge-acetaldehyde ngaphansi kwezimo eziyisisekelo. Indlela ethile yokulungiselela ingase ibe ukuthi i-pyridine ne-acetaldehyde ziyashiswa ukuze zisabele kusixazululo se-alkaline buffer, futhi umkhiqizo uhlanzwa nge-crystallization ukuze uthole (S) -2-(1-Hydroxyethyl) pyridine ngokuhlanzeka okuphezulu.
Mayelana nolwazi lokuphepha lwe-(S)-2-(1-Hydroxyethyl)pyridine, iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye nezinga lokushisa eliphezulu. Sebenzisa ngokucophelela ukugwema ukuhogela, ukugwinya nokuthinta isikhumba. Gqoka okokuvikela okufanelekile njengamagilavu okuvikela amakhemikhali kanye nezibuko ngesikhathi sokusebenza. Gcina endaweni epholile, engenamoya, futhi kude nama-oxidants nama-asidi aqinile nama-alkali. Uma ngephutha wachaphaza emehlweni noma isikhumba, kufanele ngokushesha hashaza ngamanzi amaningi, kanye nokwelashwa ngesikhathi. Ekusetshenzisweni nasekugcinweni, ukulandela ngokuqinile izinqubo zokuphepha.
