Taw qhia
2-Fluoronicotinic acid yog cov organic compound nrog cov tshuaj formula C6H4FNO2. Nws yog ib tug derivative ntawm nicotinic acid (3-oxopyridine-4-carboxylic acid) nyob rau hauv nws cov qauv tshuaj, nyob rau hauv uas ib tug hydrogen atom yog hloov los ntawm ib tug fluorine atom.
2-Fluoronicotinic acid yog dawb crystalline khoom uas ruaj khov ntawm qhov kub thiab txias. Nws muaj qhov zoo solubility thiab tuaj yeem yaj hauv dej. Nws yog ib qho tsis muaj zog acid uas tsim cov ntsev nrog cov hlau.
2-Fluoronicotinic acid yog siv dav hauv qee qhov chaw. Nws tuaj yeem siv los ua ib qho tseem ceeb hauv nruab nrab ntawm cov organic synthesis rau kev npaj ntawm lwm cov tebchaw lossis tshuaj. Tsis tas li ntawd, nws kuj tuaj yeem siv rau hauv kev sib koom ua ke ntawm hlau thiab cov tshuaj tiv thaiv catalytic.
Muaj ntau txoj hauv kev los npaj 2-Fluoronicotinic acid. Ib txoj hauv kev yog los ntawm fluorination ntawm nicotinic acid. Ib txoj hauv kev yog cov tshuaj fluorinating reagent, xws li hydrogen fluoride los yog trifluoroacetic acid, nrog nicotinic acid nyob rau hauv acidic tej yam kev mob muab 2-Fluoronicotinic acid.
Kev saib xyuas kev nyab xeeb yog xav tau thaum tuav 2-Fluoronicotinic acid. Nws yog ib qho corrosive compound thiab yuav tsum tau hnav nrog cov hnab looj tes tiv thaiv thiab tsom iav. Tsis txhob nqus nws cov plua plav lossis vapor thaum siv, thiab tswj kom muaj qhov cua zoo hauv chav kuaj. Thaum khaws cia, nws yuav tsum tau khaws cia rau hauv lub thawv qhuav, kaw, kom deb ntawm cov khoom siv hluav taws xob thiab oxidants.
Feem ntau, 2-Fluoronicotinic acid yog cov organic compound nrog zoo solubility thiab stability. Nws muaj ntau yam kev siv hauv cov organic synthesis, hlau sib koom tes thiab cov tshuaj tiv thaiv catalytic, tab sis yuav tsum tau ceev faj txog kev nyab xeeb thaum tuav thiab khaws cia.
