Hordhac
2-Bromo-4-methyl-5-nitropyridine waa unug dabiici ah. Kuwa soo socdaa waa hordhac dabeecadeeda, isticmaalkeeda, habka diyaarinta iyo macluumaadka badbaadada:
Tayada:
2-Bromo-4-methyl-5-nitropyridine waa walax adag oo leh kiristaalo huruud ah. Heerkulka qolka, waa dhif inay ku milmaan biyaha, laakiin waxay noqon kartaa mid ku milma dareerayaasha organic sida ethanol iyo dimethylformamide.
Isticmaal:
Xaruntan waxaa inta badan loo isticmaalaa sidii dhex dhexaad u ah isku-dhafka dabiiciga ah. Waxaa loo isticmaali karaa diyaarinta xeryahooda heterocyclic ee kale ee nitrogen-ku jira, sida pyrroles iyo indoles.
Habka:
2-Bromo-4-methyl-5-nitropyridine waxaa lagu diyaarin karaa falcelinta beddelka ee aniline. Xaaladaha ku habboon, aniline waxaa lagu falceliyaa bromoacetic acid si loo soo saaro 2-bromoaniline. Kadib, alkylation ee xaaladaha alkaline, 2-bromoaniline waa alkylated si loo helo 2-bromo-4-methylaniline. Natiijada 2-bromo-4-methylaniline waxaa lagu nadiifiyaa nitrification si loo helo 2-bromo-4-methyl-5-nitropyridine.
Macluumaadka Badbaadada:
2-Bromo-4-methyl-5-nitropyridine waa unug dabiici ah waana in la kaydiyaa oo si sax ah loo isticmaalo. Waa walax gubanaysa waana in laga fogeeyo ololka furan iyo kulaylka sareeyo. Inta lagu jiro qaliinka, waa in laga fogaadaa taabashada maqaarka, indhaha, iyo mareenka neefsashada, waana in qaliin lagu sameeyaa xaalado hawo leh. Gacan-gashiyada, muraayadaha indhaha iyo maaskaro waa in la xidho marka la isticmaalayo. Haddii ay dhacdo taabasho shil ah, isla markiiba ku raaci biyo badan oo raadso daryeel caafimaad.
