ʻO 5-Bromo-2,4-dichloropyrimidine kahi mea hoʻohui.

 

ʻAno maikaʻi:

- Keʻano: 5-Bromo-2,4-dichloropyrimidine he paʻa keʻokeʻo keʻokeʻo.

- Solubility: 5-Bromo-2,4-dichloropyrimidine he haʻahaʻa haʻahaʻa i ka wai a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka acetone.

 

E hoʻohana:

- Pesticides: 5-bromo-2,4-dichloropyrimidine hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana pesticide o nā pūhui heterocyclic, ka mea nui no ka hoʻomalu ʻana i nā nāhelehele wai a me nā mauhele ākea ākea.

 

Hanana:

Hiki ke hanaʻia ka synthesis o 5-bromo-2,4-dichloropyrimidine e nāʻano likeʻole,ʻo keʻano maʻamau ka hanaʻana i ka 2,4-dichloropyrimidine me ka bromine. Hoʻopili pinepine ʻia kēia hopena e ka sodium bromide.

 

ʻIke palekana:

- 5-Bromo-2,4-dichloropyrimidine hiki ke decompose i nā wela kiʻekiʻe, e hana ana i ke kinoea hydrogen chloride ʻawaʻawa. Pono e pale ʻia nā wela kiʻekiʻe a me nā waikawa ikaika i ka wā e mālama ai a mālama ʻia.

- ʻO 5-Bromo-2,4-dichloropyrimidine ka mea hoʻonāukiuki i nā maka a me ka ʻili a pono e pale ʻia. Pono e ʻaʻahu ʻia nā mīkina lima pale kūpono, nā aniani, a me ke kapa komo i ka wā e hana ai.
