Hoʻolauna
ʻO ka 3-Bromo-5-methyl-pyridine he mea hoʻohuihui mea ola me kahi ʻano kemika o C6H6BrN a me ke kaumaha molekala o 173.03g/mol. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Nani: ʻAʻole waihoʻoluʻu i ka wai melemele ʻeleʻele a i ʻole ka paʻa crystalline.
-Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik, e like me nā ʻawaʻawa, ethers a me nā hydrocarbons chlorinated.
-Ka helu heheʻe: ma kahi o 14-15 ℃.
-Pila paila: ma kahi o 206-208 ℃.
-Density: ma kahi o 1.49g/cm³.
-ʻala: he ʻala kūikawā a hoʻoulu.
E hoʻohana:
- Hoʻohana mau ʻia ʻo 3-Bromo-5-methyl-pyridine ma ke ʻano he waena i ka synthesis organik a hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pūhui organik ʻē aʻe, e like me nā lāʻau lapaʻau, pesticides a me nā mea hoʻonaninani.
-Hiki ke hoʻohana ʻia ma ke ʻano he reagent i ka noiʻi a me ka hale hana.
Kaʻina hoʻomākaukau:
- Hiki ke hoʻopili ʻia ka 3-Bromo-5-methyl-pyridine e nā ʻano ʻano like ʻole, hoʻohana maʻamau ʻia kekahi o ia ma ka hoʻohui ʻana i kahi mea methylating agent (e like me ka methyl magnesium bromide) i ka 3-bromopyridine.
ʻIke palekana:
- Pono e hoʻohana ʻia ka 3-Bromo-5-methyl-pyridine e like me nā kaʻina hana palekana kūpono, e like me ke komo ʻana i nā lako pale pilikino i koi ʻia i loko o nā laboratories kemika.
-Hiki paha ia i ka huhū a me ka pōʻino i ka maka, ka ʻili a me ka ʻōnaehana hanu. E hoʻomaʻemaʻe koke i ka wahi i hoʻopilikia ʻia a e ʻimi i ke kōkua olakino inā pono.
-I ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia i loko o kahi pahu i pani ʻia, mai ke ahi a me ka wela kiʻekiʻe.
-I ka wā e hoʻolei ai i ka ʻōpala, e hoʻokō i nā lula kūloko a lawe i nā hana palekana kaiapuni kūpono.
