Hoʻolauna

ʻO 5-Bromo-2,2-difluoro-1,3-benzodioxazole, i ʻike ʻia ʻo 5-Bromo-2,2-difluoro-1,3-benzodioxazole, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: ʻAʻole waihoʻoluʻu i nā kristal melemele māmā

- Hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ether, acetone a me ka methylene chloride

 

E hoʻohana:

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 5-Bromo-2,2-difluoro-1,3-benzodioxazole ma nā ʻano like ʻole, a loaʻa ke ʻano maʻamau ma ka hana ʻana i nā mea maka e pili ana ma lalo o nā kūlana kūpono.

- Hiki i ke kaʻina hana hoʻomākaukau ke hoʻokomo i ka hopena multi-step e pili ana i nā ʻanuʻu e like me ka hoʻololi, fluorination, a me ka bromination.

 

ʻIke palekana:

- He palena iki ka ʻike palekana ma ka 5-bromo-2,2-difluoro-1,3-benzodioxazole a pono e akahele i ka wā e hoʻohana ai a mālama ʻia paha.

- He puʻupuʻu weliweli ia i hiki ke hoʻopōʻino i ke kanaka a me ke kaiapuni.

- I ka hana ʻana i nā hana hoʻokolohua, e hahai i nā kaʻina hana palekana kūpono a me nā alakaʻi hana, me ke komo ʻana i nā lako pale pilikino kūpono (e laʻa, nā mīkina lima, nā maka pale, a me nā lole lab).

- E mālama iā ia i loko o kahi pahu paʻa i ka ea a mālama iā ia mai nā mea e like me ke ahi, ka wela, a me nā mea ʻona.

- I ka wā e hoʻolei ai i ka ʻōpala, e ʻoluʻolu e hahai i nā ʻano hana hoʻolei kūpono a e hoʻolei pono iā ia e like me nā kānāwai kūloko.
