Intangiriro
3-Bromo-5-nitro-2-hydroxypyridine ni urugingo ngengabuzima rukunze kwitwa BNHO.
Ibyiza: Kugaragara:
- Kugaragara: BNHO ni umuhondo wijimye wijimye cyangwa ifu ya kristaline.
- Gukemuka: irashobora gushonga gato mumazi, gushonga muri alcool, ether nibindi bimera.
Ikoreshwa:
- Ibikoresho byica udukoko twangiza udukoko: BNHO irashobora gukoreshwa nkibikoresho fatizo muguhuza imiti yica udukoko.
Uburyo bwo kwitegura:
Hariho uburyo bubiri busanzwe bwo gutegura: bumwe ni binyuze muri alkylation reaction ya bromobenzene na 2-hydroxypyridine kugirango ubone 3-bromo-2-hydroxypyridine, hanyuma ukore hamwe na aside nitricike kugirango ubone 3-bromo-5-nitro-2-hydroxypyridine. Ibindi ni muburyo bwa reaction ya 2-bromo-3-methylpyridine hamwe na aside nitricike kugirango ibone 3-bromo-5-nitro-2-hydroxypyridine.
Amakuru yumutekano:
- BNHO ni urugingo rwa organohalogen rufite uburozi kandi burakaza kandi ingamba zo gukingira zigomba kubahirizwa.
- Irinde guhura n'uruhu, amaso n'amasohoro; mugihe uhuye, fata ako kanya n'amazi menshi.
- Kwambara ibikoresho bikwiye byo kurinda umuntu, nka gants ya laboratoire hamwe nikirahure cyumutekano, mugihe ukoresheje no kubitegura.
- Irinde guhumeka imyuka cyangwa ivumbi kandi ukorere ahantu hafite umwuka mwiza.
- Igomba kubikwa ahantu humye, ikonje kandi ihumeka kure yumuriro cyangwa ibikoresho bya okiside.
