5-Choro-6-methoxynicotinic acid (CAS# 884494-85-3)

Mawu Oyamba

5-chloro-6-methoxyniacin ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

Katundu: 5-Chloro-6-methoxynicotinic acid ndi ufa wa crystalline woyera kapena wosayera. Imasungunuka mu zosungunulira za organic monga ethanol, acetone, ndi methanol kutentha kwachipinda, ndipo imakhala ndi kusungunuka kochepa m'madzi. Ili ndi zinthu zina za nicotinic ndi mawonekedwe a methoxy.

Njira: Kaphatikizidwe ka 5-chloro-6-methoxynicotinic acid nthawi zambiri amapezedwa ndi chlorination wa methoxynicotinic acid. Njira yodziwika bwino yokonzekera ndikuyankhira methoxyniacin ndi thionyl chloride kuti ipange 5-chloro-6-methoxyniacin.

Chidziwitso pachitetezo: 5-Chloro-6-methoxyniacin nthawi zambiri imakhala yotetezeka pakagwiritsidwe ntchito bwino, koma kusamala koyenera kumafunikabe. Pewani kukhudzana mwachindunji ndi khungu, maso, ndi thirakiti la kupuma kuti mupewe kupsa mtima kapena kusamva bwino. Zida zodzitetezera zoyenera monga magolovesi a labu, magalasi, ndi masks oteteza ziyenera kuvalidwa zikagwiritsidwa ntchito. Chisamaliro chiyenera kutengedwa kuti tipewe zoopsa zomwe zimadza chifukwa cha kuyatsa ndi magetsi osasunthika panthawi yosungira ndikugwira.
