3-BROMO-2-CHLORO-5-NITRO-6-PICOLINE(CAS# 856834-95-2) gabatarwa

3-Bromo-2-chloro-6-methyl-5-nitropyridine wani abu ne na halitta. Mai zuwa shine gabatarwa ga kaddarorin sa, amfaninsa, hanyoyin masana'anta da bayanan aminci:

inganci:
- Bayyanar: 3-Bromo-2-chloro-6-methyl-5-nitropyridine fari zuwa haske rawaya m foda.
- Solubility: Yana da kyawawa mai kyau a cikin abubuwan kaushi na halitta kamar ethanol, dimethylformamide da chloroform, amma yana da ƙarancin solubility a cikin ruwa.

Amfani:
- Maganin kashe kwari: Hakanan ana iya amfani da shi azaman ɗanyen kayan aiki ko tsaka-tsaki don maganin kashe qwari a cikin shirye-shiryen maganin kwari da fungicides.

Hanya:
Shirye-shiryen 3-bromo-2-chloro-6-methyl-5-nitropyridine ana iya aiwatar da su ta hanyoyi masu zuwa:
2-methyl-3-nitropyridine an narkar da shi a cikin ethanol kuma an ƙara yawan sulfuric acid don haɓaka halayen.
An kwantar da cakudawar dauki kuma an bi da shi tare da thionyl chloride da magnesium bromide.
An diluted cakuda dauki, sa'an nan kuma samfurin ya tsarkake ta hanyar evaporation da crystallization.
Ta hanyar tacewa, bushewa da buguwa, ana samun samfurin 3-bromo-2-chloro-6-methyl-5-nitropyridine na ƙarshe.

Bayanin Tsaro:
- 3-Bromo-2-chloro-6-methyl-5-nitropyridine mai ƙarfi ne mai ƙonewa kuma yana guje wa haɗuwa da hanyoyin kunna wuta.
- Ya kamata a dauki iskar iska mai kyau yayin sarrafawa kuma a yi amfani da kayan kariya na sirri kamar safar hannu da tabarau.
- A guji shakar ƙura ko cudanya da fata da idanu, kuma a guji sha da gangan.
- Da fatan za a adana da kyau, nesa da wuta da abubuwa masu ƙonewa, da nesa da yara da dabbobi.
