ʻO ka 2-Amino-3,5-dibromo-4-methylpyridine kahi hui kūlohelohe.

 

ʻAno maikaʻi:

Nānā: Paʻa keʻokeʻo keʻokeʻo.

Solubility: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka chloroform, ethanol a me ka etera, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

E hoʻohana:

Hoʻohana maʻamau ʻia ʻo 2-Amino-3,5-dibromo-4-methylpyridine ma ke ʻano he mea hoʻomaka a i ʻole reagent no ka synthesis organik i loko o nā laboratories kemika. Hiki ke hoʻohana i ka synthesis o pyridine derivatives, imidazole pūhui, pyridine imidazole pūhui, etc.

 

Hanana:

Hiki ke hoʻohui ʻia ka 2-Amino-3,5-dibromo-4-methylpyridine e nā pae aʻe:

Hoʻopili ʻia ka 3,5-dibromopyridine a me ka methylpyruvate ma lalo o nā kūlana alkaline e hana i ka 2-bromo-3,5-dimethylpyridine.

Hoʻopili ʻia ka 2-Bromo-3,5-dimethylpyridine me ka amonia i loko o ka chloroform e hana i ka 2-amino-3,5-dimethylpyridine.

Hoʻopili ʻia ka 2-amino-3,5-dimethylpyridine me ka hydrogen bromide e hana i ka 2-amino-3,5-dibromo-4-methylpyridine.

 

ʻIke palekana:

I ka lawelawe ʻana i ka 2-amino-3,5-dibromo-4-methylpyridine, pono e hoʻomanaʻo ʻia kēia mau mea palekana:

E pale i ka inhalation, pili i ka ʻili, a me ka ʻai ʻana. Pono e hoʻohana i nā mīkina lima pale, nā makaaniani palekana a me nā pale pale.

Pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia e pale aku i ka hoʻohu ʻana i kona mau mahu.

Pono e mālama ʻia mai ke ahi, ka wela a me nā oxidants.

ʻAʻole loa e hui pū me nā oxidants ikaika, nā mea hoʻohaʻahaʻa a me nā waikawa ikaika.

Pono e mālama ʻia ma kahi maloʻo, ʻoluʻolu, ea, kahi mamao mai ke ahi a me nā kumu wela.
