(S)-(-)-2-(1-Hydroxyethyl)pyridine (CAS# 59042-90-9)

Hordhac

(S)-2-(1-Hydroxyethyl) pyridine waa iskudhis ka samaysan chiral oo leh qaacidada kiimikaad ee C7H9NO waxayna leedahay sifooyin indhaha ah. Waxay leedahay laba stereoisomers, kuwaas oo (S) -2- (1-Hydroxyethyl) pyridine uu yahay mid. Waa dareere aan midab lahayn ama huruud ah oo leh ur gaar ah.

(S)-2- (1-Hydroxyethyl) pyridine waxaa inta badan loo istcimaalaa kiral inducer ama kiciya in synthesis organic. Waxaa loo isticmaali karaa isku-darka xeryahooda kale ee stereoisomer, kicinta falcelinta isku-darka dabiiciga ah, isku-darka daroogada iyo wixii la mid ah.

Diyaarinta (S) -2- (1-Hydroxyethyl) pyridine guud ahaan waxaa lagu helaa falcelinta pyridine leh acetaldehyde ee xaaladaha aasaasiga ah. Habka diyaarinta gaarka ah wuxuu noqon karaa in pyridine iyo acetaldehyde ay kuleylaan si ay uga falceliyaan xalalka alkaline-ka, iyo badeecada waxaa lagu nadiifiyaa crystallization si loo helo (S) -2- (1-Hydroxyethyl) pyridine oo leh nadiif sare.

Marka la eego macluumaadka badbaadada (S) -2- (1-Hydroxyethyl) pyridine, waa dareere guban kara waana in laga fogeeyaa ololka furan iyo heerkulka sare. Si taxaddar leh u isticmaal si aad uga fogaato neefsashada, liqidda iyo maqaarka oo taabto. Xiro qalab ilaalin ku habboon sida galoofyada difaaca kiimikaad iyo muraayadaha indhaha inta lagu jiro hawlgalka. Ku kaydi meel qabow, hawo leh, oo ka fog oksaydhiyeyaasha iyo asiidhka xooggan iyo alkalis. Haddii si lama filaan ah indhaha ama maqaarka loogu firdhiyo, waa in isla markiiba lagu tirtiraa biyo badan, iyo daaweyn caafimaad oo waqtigeeda ku habboon. Isticmaalka iyo kaydinta, si adag loo raaco nidaamka badbaadada.
