-Njupụta: ihe dịka 1.49g/cm³.
-isi: nwere isi pụrụ iche na-akpali akpali.
Jiri:
- A na-ejikarị 3-Bromo-5-methyl-pyridine eme ihe dị ka onye na-ahụ maka ihe ndị na-emepụta ihe na-edozi ahụ ma nwee ike iji kwadebe ogige ndị ọzọ, dị ka ọgwụ, pesticides na dyes.
-Ọ nwekwara ike-eji dị ka a reagent na nnyocha na laabu.
Ụzọ nkwadebe:
- 3-Bromo-5-methyl-pyridine nwere ike ịmepụta ya site na ụzọ dị iche iche, otu n'ime ha na-ejikarị eme ihe site n'ịgbakwunye onye na-ahụ maka methylating (dị ka methyl magnesium bromide) na 3-bromopyridine.
Ozi nchekwa:
- Ekwesịrị iji 3-Bromo-5-methyl-pyridine dị ka usoro nchekwa kwesịrị ekwesị si dị, dị ka iyi ihe nchebe onwe onye achọrọ na ụlọ nyocha kemịkalụ.
-Ọ nwere ike ịkpasu iwe na mebie anya, akpụkpọ ahụ na usoro iku ume. Hichaa ebe emetụtara ozugbo wee chọọ enyemaka ahụike ma ọ bụrụ na ọ dị mkpa.
- Mgbe ị na-echekwa ma na-edozi ya, a ga-echekwa ya n'ime akpa mechiri emechi, pụọ na ọkụ na oke okpomọkụ.
-Mgbe ị na-ekpofu ihe mkpofu, soro usoro iwu obodo wee mee usoro nchedo gburugburu ebe obibi kwesịrị ekwesị.
