2-Methoxy-5-nitropyridine CAS 5446-92-4 imapezedwa ndi etherification ya 2-chloro-5-nitropyridine. Sodium methoxide anawonjezera dropwise ku chisakanizo cha 2-chloro-5-nitropyridine ndi methanol pansi yogwira mtima, ndi makhiristo anali precipitated mu wosweka ayezi pambuyo kuwonjezera sulfure kwa 1 h. Sefa, zowumitsa, ndi kukonzanso ndi methanol kuti mupeze chomaliza. Zokolola zinali 92%.
Believe Chemical ndi mtsogoleri waku China2-Methoxy-5-nitropyridine CAS 5446-92-4wopanga, wogulitsa ndi wogulitsa kunja. Kutsatira kufunafuna zinthu zabwino kwambiri, kotero kuti 2-Methoxy-5-nitropyridine CAS 5446-92-4 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!
