Taw qhia
2-Amino-4-cyanopyridine yog cov organic compound. Nws yog dawb crystalline khoom uas yog me ntsis yaj hauv dej thiab tuaj yeem soluble hauv cov kuab tshuaj organic xws li cawv thiab ketones.
2-Amino-4-cyanopyridine tuaj yeem siv rau hauv kev sib txuas ntawm lwm cov tebchaw thiab muaj ntau yam kev siv hauv cov organic synthesis.
Kev npaj ntawm 2-amino-4-cyanopyridine tuaj yeem tau txais los ntawm hydrogenation thiab nitrosation ntawm pyridine. Ua ntej, pyridine thiab hydrogen yog hydrogenated nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst los tsim ib tug 2-amino derivative ntawm pyridine. Qhov tshwm sim 2-aminopyridine yog tom qab ntawd ua rau muaj nitrous acid los tsim 2-amino-4-cyanopyridine.
Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag vim nws yuav muaj kev cuam tshuam rau ntawm daim tawv nqaij thiab qhov muag.
Cov hnab looj tes tiv thaiv thiab looj tsom iav yuav tsum hnav thaum siv, thiab xyuas kom meej tias kev ua haujlwm tau ua nyob rau hauv qhov chaw muaj cua zoo.
Tsis txhob nqus plua plav thiab hnav daim npog qhov ncauj tiv thaiv.
Nyob rau hauv rooj plaub ntawm kev nqus pa los yog kev noj cov tshuaj no, nrhiav kev kho mob tam sim ntawd.
Thov khaws cov khoom sib xyaw kom zoo, kom deb ntawm hluav taws thiab oxidants, thiab hauv qhov chaw qhuav, txias.
