ʻO ka 2,5-dichloro-4-methylpyriridine he mea hoʻohuihui kūlohelohe me ke ʻano kemika C6H5Cl2N. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

 

1. ʻano:

-Ke ʻano: wai kala ʻole a i ʻole crystalline solid;

-Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ether, ka waiʻona a me ka hydrocarbons;

-Ka helu hoohehee:-26°C;

-Pila paila: 134-136°C;

-Ka mānoanoa: 1.36g/cm³.

 

2. hoʻohana:

ʻO -2,5-dichloro-4-methylpyriridine he mea koʻikoʻi i waena o ka synthesis organik a loaʻa i ka nui o nā noi ma ke kahua o ka lāʻau lapaʻau a me ke kemika;

-Hiki ke hoʻohana ʻia e hoʻomākaukau i nā pesticides, fungicides a me nā mea hoʻohui ʻē aʻe;

- hiki ke hoʻohana ʻia ma ke ʻano he catalyst, surfactant a me nā mea hoʻonaninani.

 

3. ʻano hoʻomākaukau:

-ʻO ke ʻano o ka hoʻomākaukau ʻana o 2,5-dichloro-4-methylpyriridine e loaʻa pinepine ʻia e ka hopena chlorination ma pyridine.

-No ka laʻana, hiki ke hoʻopili ʻia ka pyridine me ka phosphorus oxychloride (POCl3) a i ʻole phosphorus tetrachloride (PCl4) ma lalo o kahi ea inert, a ukali ʻia e ka mālama dechlorination no ka loaʻa ʻana o ka huahana.

 

4. ʻIke palekana:

ʻO -2,5-dichloro-4-methylpyriridine ka mea hoʻonāukiuki a me kaʻino i nā maka, kaʻili a me ka'ōpū hanu. Holoi me ka wai nui ma hope koke iho o ka launa ʻana a e ʻimi i ke kōkua kino;

- pono e hoʻohana i nā mīkina lima pale, nā aniani pale a me ka pale pale;

-E hōʻalo i ka hoʻopili ʻana me nā oxidants ikaika e pale i nā hopena weliweli;

- E mālama ʻia mai ke ahi, ka wela a me nā mea puhi.
