5-Amino-3-bromo-2-methoxypyridine（CAS# 53242-18-5)

Hoʻolauna

He pūhui mea ola ia me kahi ʻano kemika o C6H7BrN2O a me ke kaumaha molekala o 197.04g/mol.

ʻO nā waiwai o ka hui pū kekahi:

1. Nānā: colorless to light yellow crystal

2. wahi hehee: 110-115°C

3. wahi paila: ʻaʻohe ʻikepili

Hiki ke hoʻohana ʻia no kekahi mau hopena i ka synthesis organik, e like me ka hoʻohui ʻana i nā hopena, acyl transfer reactions o ka carboxylic acids, etc.

Hoʻopili ʻia kahi ala maʻamau no ka hoʻomākaukau ʻana i ka pūhui 2-bromo-5-aminopyridine me ka bromo methyl ether. Lawe ʻia ka hopena ma lalo o nā kūlana alkaline e hana i ka huahana i manaʻo ʻia.

E pili ana i ka ʻike palekana, he pūhui organik ia, a pono e hoʻomaopopo ʻia kēia mau mea:

1. Hiki i kēia hui ke hana i nā kinoea ʻawaʻawa ma lalo o nā kūlana wela a kiʻekiʻe paha.

2. E hoʻohana i nā mea pale kūpono, e like me nā maka aniani a me nā mīkina lima.

3. pale i ka pili ana me ka ili, ka maka a me ka hanu, e pale i ka inhalation o ka uahi/puehu/ kinoea/ mahu/puu.

4. Pono e mālama ʻia ma kahi maloʻo, sila ʻia, maikaʻi-ventilated, mamao mai nā lapalapa a me nā kumu wela.

I ka hoʻohana ʻana a i ʻole ka mālama ʻana i ka pūhui, pono ʻoe e hahai i nā lula hana palekana kūpono a nānā i ka pepa ʻikepili palekana o ka pūhui. Inā pono, e nīnau i ke kauka no ka ʻike kikoʻī.
