ʻO ka ʻakika he pūhui olaola me ke kumu kemika C6H4BrO2S.
ʻAno:
-Ke ʻano: he paʻa keʻokeʻo a melemele ka waikawa.
-Solubility: Soluble i loko o ka chloroform, acetone a me ka methane chlorinated.
-Ka helu heheʻe: ma kahi o 116-118 degere Celsius.
E hoʻohana:
-e hoʻohana pinepine ʻia ka waikawa ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik.
-Hiki ke hoʻohana ʻia no ke kūkulu ʻana i nā pūhui organik i loaʻa nā hale apo thiophene.
Ke Kaʻina Hoʻomākaukau: Nui nā ʻano synthetic o
-anacid. ʻO kekahi o nā ʻano hana maʻamau ka hoʻohana ʻana i ka waikawa bromoacetic ma ke ʻano he mea maka, e hoʻopili me ka thiophene ma lalo o nā kūlana alkaline e hoʻohua ai i ka 3-bromothiophene, a laila e hoʻokō i ka hopena carboxylic ma lalo o nā kūlana acidic.
ʻIke palekana:
-e hoʻonāukiuki paha ka ʻakika i ka maka, ka ʻili a me ka ʻōnaehana hanu.
-I ka wā e hoʻohana ai, pono e mālama ʻia e pale aku i ka inhalation o ka lepo a i ʻole ka pili ʻana me ka ʻili a me nā maka.
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima lab, nā maka aniani a me nā pale alo ma mua o ka hana.
-Inā pili me ka ʻili a i ʻole nā maka, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau. E hāʻawi ʻia nā hana kōkua mua kūpono inā pono.
