I-2-Methoxy-5-nitropyridine CAS 5446-92-4 ifunyenwe nge-etherification ye-2-chloro-5-nitropyridine. I-sodium methoxide yongezwa kwi-dropwise kumxube we-2-chloro-5-nitropyridine kunye ne-methanol phantsi kokuvuselela, kunye neekristali zatshitshiswa kwiqhwa elityumkileyo emva kokongeza isulfure kwi-1 h. Hlunga, yome, kwaye uphinde udibanise nge-methanol ukufumana imveliso egqityiweyo. Isivuno sasingama-92%.
I-Believe Chemical yi-China ehamba phambiliI-I-2-Methoxy-5-nitropyridine CAS 5446-92-4umenzi, umthengisi kunye nomthumeli ngaphandle. Ukubambelela ekufuneni umgangatho ogqibeleleyo weemveliso, ukwenzela ukuba i-2-Methoxy-5-nitropyridine CAS 5446-92-4 iye yaneliswa ngabathengi abaninzi. Shandong Kholwa
Silungile kwiingenelo zeemveliso zemichiza kwintsimi. Iimveliso zethu zithunyelwa eYurophu, eUnited States, Japan, South Korea, Southeast Asia nakwamanye amazwe kunye nemimandla. Ngenzululwazi kunye netekhnoloji njengesikhokelo, ukunyaniseka njengesiseko, umgangatho njengobomi, kunye nokuthembela kwingqikelelo yeshishini lokusungula izinto ezintsha kunye nophuhliso, sinethemba elinyanisekileyo lokuseka utshintshiselwano kunye nentsebenziswano ebanzi kunye nabathengi basekhaya nabangaphandle ukudala impumelelo!
