Hordhac
2,5-Dibromo-4-methylpyridine waa unug dabiici ah. Kuwa soo socdaa waa horudhac tafatiran oo ku saabsan guryaha, isticmaalkooda, hababka diyaarinta iyo macluumaadka badbaadada xaruntan:
Tayada:
2,5-Dibromo-4-methylpyridine waa mid adag oo aan midab lahayn iyo foomamka crystalline jaalaha ah. Waxay leedahay milmayn xooggan waxayna ku milmaysaa dareerayaal badan oo dabiici ah. Waa xarun aan degganayn oo si fudud u burburta iftiinka qorraxda.
Isticmaal:
Xaruntan waxaa inta badan loo isticmaalaa sida walxo ceeriin ah iyo reagent marka la isku daro organic.
Habka:
2,5-Dibromo-4-methylpyridine waxaa inta badan lagu diyaariyaa falcelinta p-toluene brominated iyo pyridine. P-toluene waxay la falgashaa koobabka bromide si ay u sameyso 2-bromotoluene, ka dibna waxay la falgashaa pyridine hoosta catalysis acid si ay u soo saarto badeecad kama dambays ah.
Macluumaadka Badbaadada:
2,5-Dibromo-4-methylpyridine waxay u baahan tahay in si taxadar leh loo maareeyo maadaama ay tahay iskudhis sun ah. Waa in taxaddar la sameeyaa si looga fogaado taabashada maqaarka, indhaha, iyo marinnada neefsashada marka la qalayo. Qalabka ilaalinta shakhsi ahaaneed ee habboon sida galoofyada, muraayadaha indhaha, iyo maaskaro ilaalinta waa in la gashado marka shaybaarka lagu isticmaalo. Marka la kaydiyo oo la qabto, waa in laga fogaadaa walxaha guban kara iyo walxaha oksijiinta ah. Haddii walaxda la liqo ama si qalad ah loo nuugo, waa in si degdeg ah loo raadsado daryeel caafimaad. Marka qashinka la tuurayo, waa in la raaco xeerarka deegaanka, qashinkana si fiican loo asturo si looga fogaado wasakhaynta deegaanka.
