5-Chloro-2,3-difluoropyridine CAS 89402-43-7 Meta-bromobenzoic acid waa nooc ka mid ah dhexdhexaadiyeyaasha kiimikaad ee aad muhiim u ah, kuwaas oo si ballaaran loogu isticmaalo falanqaynta iyo ogaanshaha (kimikada kimikalka), isku-darka organic iyo dhexdhexaadiyeyaasha dawooyinka (anti-rheumatic) daroogada ketoprofen, iwm.), daawaynta dardargeliyayaasha.
Believe Chemical waa hormuudka Shiinaha 5-Chloro-2,3-difluoropyridine CAS 89402-43-7 soo saaraha, alaab-qeybiyaha iyo dhoofiyaha. U hoggaansanaanta raadinta tayada qumman ee alaabta, si markaa 5-Chloro-2,3-difluoropyridine CAS 89402-43-7 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!

2,3-difluoro-5-chloropyridine waa dhexdhexaad muhiim ah oo loogu talagalay isku dhafka acetochlor ee waxtarka sare leh ee sunta cayayaanka. Tobankii sano ee la soo dhaafay, sunta cayayaanka leh ee fluorinad ayaa si degdeg ah u horumaray, waxayna noqdeen diiradda horumarinta warshadaha sunta cayayaanka ee adduunka. Waxaa ka mid ah, pyrethroids fluorinated iyo sunta cayayaanka benzoylurea fluorinated benzoylurea ayaa aad loo horumariyay oo la dabaqay.
