3-Bromo-2 6-dichloropyridine(CAS# 866755-20-6) Introduction

ʻO 3-Bromo-2,6-dichloropyridine he mea hoʻohuihui mea ola me ke ʻano kemika C5H2BrCl2N. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

- ʻO 3-Bromo-2,6-dichloropyridine kahi paʻa me ke ʻano keʻokeʻo a me ka melemele crystalline.

-ʻO kona helu heheʻe ma kahi o 60-62 degere Celsius, a ʻo kona wahi e hoʻolapalapa ai ma kahi o 240 degere Celsius.

- 3-Bromo-2,6-dichloropyridine 'a'ole hiki ke ho'ohehe'e 'ia i ka wai, akā hiki ke ho'ohehe'e 'ia i loko o nā mea ho'ohenehene e like me ka ethanol a me ka dimethylformamide (DMF).

 

E hoʻohana:

- 3-Bromo-2,6-dichloropyridine he mea koʻikoʻi koʻikoʻi koʻikoʻi synthesis intermediate, hoʻohana nui ʻia i ka pesticide, pharmaceutical a me nā ʻoihana kemika.

-Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka synthesis o nā pūhui ʻē aʻe, e like me nā pesticides, nā lāʻau anti-cancer a me nā dyes fluorescent.

 

Kaʻina hoʻomākaukau:

Hiki ke loaʻa ka hoʻomākaukau ʻana o -3-Bromo-2,6-dichloropyridine ma ka hana ʻana i ka 2,6-dichloropyridine me ka bromine.

-ʻO nā kūlana hopena e pono ai ka hoʻomehana a lawe ʻia i loko o kahi solvent kūpono e like me ka acetone a i ʻole dimethylbenzamide.

 

ʻIke palekana:

- Pono e mālama ʻia ʻo 3-Bromo-2,6-dichloropyridine i loko o kahi ʻano lepo lepo a mālama ʻia i kahi maloʻo maloʻo, mamao mai ke ahi a me ka wela kiʻekiʻe.

-E hoʻohana i nā lako pale pilikino kūpono e like me nā maka aniani, nā mīkina lima a me nā lole pale ke hoʻohana ʻia.

-E pale i ka pili ʻana me ka ʻili, nā maka a me ka ʻōpū hanu. Inā loaʻa ka pilikia, holoi koke me ka wai nui a ʻimi i ke kōkua olakino.

-I ka hoʻohana ʻana a me ka mālama ʻana, e hoʻolohe i ka hoʻokō ʻana i nā kaʻina hana palekana kūpono e hōʻoia i ka palekana pilikino a me ka palekana o ke kaiapuni.
