Mawu Oyamba
(S) -2- (1-Hydroxyethyl) pyridine ndi mankhwala a chiral omwe ali ndi mankhwala C7H9NO ndipo ali ndi mawonekedwe a kuwala. Ili ndi ma stereoisomers awiri, omwe (S) -2- (1-Hydroxyethyl) pyridine ndi amodzi. Ndimadzimadzi opanda mtundu mpaka achikasu okhala ndi fungo lachilendo.
(S) -2-(1-Hydroxyethyl)pyridine nthawi zambiri amagwiritsidwa ntchito ngati chiral inducer kapena chothandizira mu organic synthesis. Ikhoza kugwiritsidwa ntchito popanga zinthu zina zopangira stereoisomer, zopangira organic synthesis reaction, high-order drug synthesis ndi zina zotero.
Kukonzekera kwa (S) -2- (1-Hydroxyethyl) pyridine nthawi zambiri kumapezeka pochita pyridine ndi acetaldehyde pansi pazifukwa zofunika. Njira yeniyeni yokonzekera ikhoza kukhala kuti pyridine ndi acetaldehyde zimatenthedwa kuti zigwirizane ndi njira ya alkaline buffer, ndipo mankhwalawa amayeretsedwa ndi crystallization kuti apeze (S) -2- (1-Hydroxyethyl) pyridine ndi chiyero chachikulu.
Ponena za chidziwitso cha chitetezo cha (S) -2-(1-Hydroxyethyl)pyridine, ndi madzi oyaka moto ndipo ayenera kusungidwa kutali ndi moto wotseguka komanso kutentha kwambiri. Gwiritsani ntchito mosamala popewa kupuma, kumeza ndi kukhudza khungu. Valani zida zodzitetezera zoyenera monga magolovesi oteteza mankhwala ndi magalasi mukamagwira ntchito. Sungani pamalo ozizira, opanda mpweya wabwino, komanso kutali ndi zowonjezera zowonjezera ndi ma asidi amphamvu ndi alkalis. Ngati mwangozi splashed m'maso kapena khungu, ayenera yomweyo muzimutsuka ndi madzi ambiri, ndi yake mankhwala. Mu ntchito ndi kusunga, kutsatira mosamalitsa njira chitetezo.
