2-Cyano-5-bromomethylpyridine（CAS# 308846-06-2)

Hoʻolauna

He hui kino ia me ke kumu hoʻoheheʻe kemika o C. H brn₂. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

ʻAno:

-Ke ʻano: paʻa kala kala ʻole

-Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol a me ka dimethylformamide

-Ka helu heheʻe: ma kahi o 84-86 ℃

-Molecular kaumaha: 203.05g/mol

E hoʻohana:

Hiki ke hoʻohana ʻia -G ma ke ʻano he waena a me nā reagents i ka synthesis organik.

-Hiki ke hoʻohana ʻia e synthesize i nā pūhui organik e like me nā lāʻau lapaʻau, nā kala kala a me nā pesticides me nā hale e like me ka imidazole a me ka pyridine.

Hanana:

- Nui nā ʻano o ka synthesis, hiki ke loaʻa ma kekahi o kēia mau ala:

1. Ka hopena o 2-cyano -5-bromomethyl -1-methyl pyridine a me cyanogen bromide

2. E hana i ka 2-cyanopyridine me ka methoamine a me ka methyl bromide

3. Ka hopena o 2-bromopyridine me carbonitrile a me ka waika hydrocyanic

ʻIke palekana:

-he mea hoʻohuihui mea ola me kekahi mea ʻona.

-E hoʻohana mau i nā lako pale pilikino kūpono e like me nā mīkina lima, nā aniani a me nā ʻaʻahu lab ke lawelawe a hoʻohana.

-E hōʻalo i ka hanu ʻana, ʻai a hoʻopā paha i ka ʻili e pale aku i ka ʻona.

- E kūʻai a hoʻohana i kahi wahi palekana, e pale i ka hoʻopili ʻana me nā oxidants a me nā mea puhi.
