5-Bromo-2 4-dichloropyrimidine (CAS# 36082-50-5)
| Amakhodi Engozi | R23/24/25 – Kunobuthi ngokuhogela, ukuthintana nesikhumba futhi uma ugwinywe. R34 – Ibangela ukusha R43 - Ingabangela ukuzwela ngokuthinta isikhumba |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S27 – Khumula ngokushesha zonke izingubo ezingcolile. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) |

Isingeniso
I-5-Bromo-2,4-dichloropyrimidine iyinhlanganisela yezinto eziphilayo.
Ikhwalithi:
- Ukubukeka: I-5-Bromo-2,4-dichloropyrimidine iyi-crystalline solid solid.
- Ukunyibilika: I-5-Bromo-2,4-dichloropyrimidine inokuncibilika okuphansi emanzini futhi iyancibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-acetone.
Sebenzisa:
- Izibulala-zinambuzane: I-5-bromo-2,4-dichloropyrimidine ingasetshenziswa njengengxenye ye-pesticide ye-heterocyclic compounds, ikakhulukazi ekulawuleni ukhula lwasemanzini kanye nokhula olubanzi.
Indlela:
Ukuhlanganiswa kwe-5-bromo-2,4-dichloropyrimidine kungenziwa ngezindlela ezahlukene, indlela evamile ukuphendula i-2,4-dichloropyrimidine nge-bromine. Lokhu kusabela ngokuvamile kwenziwa yi-sodium bromide.
Ulwazi Lokuphepha:
- I-5-Bromo-2,4-dichloropyrimidine ingase ibole emazingeni okushisa aphezulu, ikhiqize igesi enobuthi ye-hydrogen chloride. Amazinga okushisa aphezulu nama-asidi aqinile kufanele kugwenywe ngesikhathi sokuphatha nokugcina.
- I-5-Bromo-2,4-dichloropyrimidine iyacasula emehlweni nasesikhumbeni futhi kufanele igwenywe. Amagilavu okuzivikela afanelekile, izibuko, nejazi lelebhu kufanele kugqokwe ngesikhathi sokusebenza.
