ʻO 4, he mea hoʻohui kino me ke kumu hoʻohālike kemika C7H3Cl2N. He hoʻolauna kēia i kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana: Nature:
-Hōʻike: 4, he wai kalamele ʻole ia.
-Solubility: Loaʻa ka solubility maikaʻi i nā mea hoʻoheheʻe organik maʻamau.
-Ka helu hoʻoheheʻe a me ka helu hoʻolapalapa: ʻo ka helu hoʻoheheʻe -10 ℃, ʻo ka helu hoʻolapalapa ʻo 230-231 ℃.
-Ka mānoanoa: 1.44g/cm³ (20°C).
-Stability: He kūpaʻa ia, akā e pale i ka pilina me nā oxidants ikaika.

E hoʻohana:
- 4, hoʻohana pinepine ʻia ma ke ʻano he reagent a waena i ka synthesis organik.
-Hiki ke hoʻohana ʻia e synthesize i nā lāʻau e like me ka carbamazepine.
- hiki ke hoʻohana ʻia e synthesize i nā ʻano pesticides a me nā mea hoʻonaninani.

Hanana:
- 4, ʻo ka hoʻomākaukau ʻana o ka mea maʻamau e loaʻa i ka hopena chlorination hapa o ka pyridine.
-ʻO ke ʻano hoʻomākaukau kūikawā hiki ke hana i ka pyridine me ka benzyl chloride ma lalo o ka catalysis acid, a laila hydrolyze me ka concentrated aqueous hydrochloric acid e loaʻa ai 4.

ʻIke palekana:
- 4, he hui kino. Hōʻalo i ka inhalation, ingestion a i ʻole pili ʻili.
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima lab, nā maka aniani a me nā lole pale i ka wā e hoʻohana ai.
-Ina pili i ka ili a me na maka, holoi koke me ka wai nui a imi i ke kokua kino.
-E hahai i nā kaʻina hana palekana i ka wā o ka mālama ʻana a me ka mālama ʻana, a pale i ka waiho ʻana me nā kumu hoʻāla a i ʻole nā ​​​​mea hoʻomake ikaika.
