Ọ bụ ngwakọta organic nwere usoro kemịkalụ C8H9NO3. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
- Ọdịdị: Ọ bụ enweghị agba ka ìhè edo edo crystalline siri ike.
-Solubility: Ọ fọrọ nke nta ka ọ bụrụ ihe a na-apụghị imeri emeri na mmiri, ma ọ nwere mma solubility na organic solvents dị ka ethanol na dimethylformamide.
- Ebe mgbaze: Ebe mgbaze bụ ihe dịka 72-75 degrees Celsius.
Jiri:
- Ngwakọta kemịkalụ: Ọ bụ ogige etiti a na-ejikarị eme ihe nke enwere ike iji mejupụta ogige organic ndị ọzọ.
-Research: Enwere ike iji ya maka mmeghachi omume njikọ organic na nyocha ụlọ nyocha ndị ọzọ.
Ụzọ nkwadebe:
Enwere ike ime synthesis site na usoro ndị a:
1. Nke mbụ, a na-enweta 2-methyloxy-5-nitropyridine site na imeghachi 2-methyloxy-5-nitropyridine na nitric acid.
2. Mgbe ahụ meghachi omume 2-methoxy-5-nitropyridine na reagent methylating (dị ka methyl sodium iodide) iji nweta ngwaahịa ikpeazụ.
Ozi nchekwa:
Data nchekwa dị oke, mana ọ nwere ike ịbụ ihe na-egbu egbu nye mmadụ na gburugburu ebe obibi. Mgbe ị na-eji ya, kwesịrị ịgbaso omume ụlọ nyocha kwesịrị ekwesị, ma were usoro nchedo onwe onye dị mkpa, dị ka iyi mkpuchi mkpuchi na uwe aka.
