2-Amino-5-nitropyridine CAS 4214-76-0 imachokera ku nitration ya 2-aminopyridine. Pa kutentha kwa 50 °C, 2-aminopyridine inawonjezeredwa ku asidi sulfuric woyikirapo, kenako fuming nitric acid anawonjezedwa dropwise, ndi kutentha sikunapitirire 50 °C. Yalirani pa 45 ° C kwa 2h, ndikuyambitsa kutentha kwa 4h. Njira yothetsera idatsanuliridwa mu ayezi wophwanyidwa, ndipo pH idasinthidwa kukhala 6 powonjezera madzi ammonia pansi pa 5 ° C, ndipo makhiristo adawomberedwa. Sefa ndi kuyanika. Recrystallization ndi madzi kuti mupeze mapulateleti otumbululuka achikasu, perekani 75%
Believe Chemical ndiwopanga China 2-Amino-5-nitropyridine CAS 4214-76-0 wopanga, wogulitsa ndi kutumiza kunja. Kutsatira kufunafuna zinthu zabwino kwambiri, kotero kuti 2-Amino-5-nitropyridine CAS 4214-76-0 yathu yakhutitsidwa ndi makasitomala ambiri. Shandong Khulupirirani
Ndife abwino pa ubwino wa mankhwala mankhwala m'munda. Zogulitsa zathu zimatumizidwa ku Europe, United States, Japan, South Korea, Southeast Asia ndi mayiko ena ndi zigawo. Ndi sayansi ndi luso monga kalozera, kukhulupirika monga maziko, khalidwe moyo, ndi kudalira lingaliro ogwira ntchito za luso ndi chitukuko, ife moona mtima tikuyembekeza kukhazikitsa kusinthanitsa ndi mgwirizano waukulu ndi makasitomala m'nyumba ndi akunja kulenga chitukuko!
