2-Amino-5-nitropyridine CAS 4214-76-0 waxaa laga soo qaatay nitration of 2-aminopyridine. Heerkulka 50 °C, 2-aminopyridine ayaa lagu daray sulfuric acid xoog leh, ka dibna qiiqa nitric acid ayaa lagu daray hoos, heerkulkuna ma dhaafin 50 ° C. Ku dhaji 45 ° C ilaa 2 saacadood, ku walaaq heerkulka qolka 4 saacadood. Xalka falcelinta waxaa lagu shubay baraf la jajabiyey, pH-na waxaa lagu hagaajiyay 6 iyadoo lagu daray biyaha ammonia ee ka hooseeya 5 ° C, iyo kiristaalo ayaa la soo dajiyay. Sifee oo qalaji. Dib u recystallization oo biyo ah si loo helo platelet jaale ah oo cirro leh, waxay dhalisaa 75%
Believe Chemical waa hormoodka Shiinaha 2-Amino-5-nitropyridine CAS 4214-76-0 soo saare, alaab-qeybiye iyo dhoofiye. U hoggaansanaanta raadinta tayada qumman ee alaabta, si 2-Amino-5-nitropyridine CAS 4214-76-0 ay ku qanacsan yihiin macaamiil badan. Shandong Rumayso
Waxaan ku fiicanahay faa'iidooyinka alaabta kiimikada ee goobta. Alaabadayada waxaa loo dhoofiyaa Yurub, Mareykanka, Japan, Kuuriyada Koonfureed, Koonfur-bari Aasiya iyo dalal kale iyo gobollada. Iyada oo sayniska iyo tignoolajiyada ay yihiin hagaha, daacadnimada aasaaska, tayada nolosha, iyo ku tiirsanaanta fikradda ganacsi ee hal-abuurka iyo horumarka, waxaan si dhab ah u rajaynaynaa in aan abuurno is-weydaarsi iyo iskaashi ballaaran oo lala yeesho macaamiisha gudaha iyo kuwa shisheeye si loo abuuro barwaaqo!
