3 5-DIBROMO-4-CHLOROPYRIDINE (CAS# 13626-17-0) hoʻolauna
ʻO 4-chloro-3,5-dibromopyridine (ʻike pū ʻia ʻo 4-chloro-3,5-dibromopyridine) he mea hoʻohuihui. Eia ka ʻike e pili ana i nā waiwai, nā hoʻohana, nā ʻano hoʻomākaukau, a me ka palekana o ka pūhui:
ʻano:
-Nani: 4-chloro-3,5-dibromopyridine he kala ʻole i ke aniani melemele a i ʻole ka pauka crystalline.
-Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, acetone, a me ka etera.
-Nā waiwai kemika: He kumu nāwaliwali ia e hiki ke hoʻololi i nā hopena, ka hoʻopaʻa hydrogen, a me nā hopena nucleophilic succinyl.
Ke kumu:
-Hiki ke hoʻohana ʻia ma ke ʻano he reagent i loko o nā laboratories kemika.
ʻano hana hana:
-4-chloro-3,5-dibromopyridine hiki ke synthesized ma ka hoʻohui ʻana i ka cuprous chloride (CuCl) i ka 3,5-dibromopyridine a me ka hoʻomehana ʻana i ka hopena.
- Hiki ke hoʻololi ʻia ke ʻano synthesis kikoʻī e like me ka mea e pono ai, no ka mea hiki ke hoʻomaikaʻi ʻia ke ʻano synthesis o nā pūhui e like me nā kūlana like ʻole a me nā koi ʻana.
ʻIke palekana:
ʻO -4-chloro-3,5-dibromopyridine kekahi mea ʻawaʻawa i ke kino o ke kanaka, a ʻo ka hoʻopili ʻana a i ʻole ka inhalation hiki ke hōʻeha a hōʻeha.
- Pono e mālama ʻia nā hana palekana kūpono i ka wā e hoʻohana ai a mālama ai i ka pūhui, e like me ke komo ʻana i nā mīkina lima pale, nā maka aniani, a me nā lole pale.
- E ʻoluʻolu e heluhelu a hahai i ka manual hana palekana o nā kemika kūpono ma mua o ka hoʻohana ʻana, a hana i nā hoʻokolohua ma lalo o nā kūlana kūpono.
