2-Chloro-3-bromo-4-methylpyridine（CAS# 55404-31-4)

Hoʻolauna

He pūhui mea ola ia me kahi ʻano kemika o C6H5BrClN a me ke kaumaha molekala o 192.48g/mol. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

1. ʻano:

-Ke ʻano: kala ʻole i ka wai melemele māmā a paʻa paha;

-Pila paila: ma kahi o 220-222 ℃ (ma ka barometer);

-kahi hoʻoheheʻe: ma kahi o 33-35 ℃;

-Sensitive i ka malamalama, pale i ka lōʻihi i ka lā;

-Soluble i loko o nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol a me ka dimethylformamide.

2. hoʻohana:

-Ma keʻano he kikowaena: hiki ke hoʻohanaʻia no ka hoʻomākaukauʻana i nā pūhui'ē aʻe, e like me ka fluorine-containing compounds a iʻole nā ​​hua'ōlelo o nā pūhui heterocyclic'ē aʻe;

-Hoʻohana ʻia i ka synthesis organik: Hiki ke hoʻohana ʻia ma ke ʻano he reagent koʻikoʻi i ka synthesis organik e hoʻolauna i nā hui hana e like me nā mea halogen a i ʻole nā ​​hui amino.

3. Ke ʻano hoʻomākaukau:

Hiki ke hoʻomākaukau ʻia e ka hui pū ʻana o ka chlorination, bromination a me ka methylation o pyridine.

4. ʻIke palekana:

-he mea hoʻohuihui kino, hiki ke pilikia;

- pono e like me nā kaʻina hana palekana kemika no ka hana ʻana, e pale i ka hoʻopili pololei ʻana me ka ʻili a me nā maka;

- Pono e hāʻawi ʻia ka ventila maikaʻi i ka wā o ka hoʻohana ʻana e pale aku i ka inhalation o nā mahu;

-No ka hoʻolei ʻana i ka ʻōpala, mālama i nā lula kūloko.
