ʻO ka 2-pyridinamine, 5,6-dibromo-(2-pyridinamine, 5,6-dibromo-) he hui lāʻau me ke ʻano kemika C5H5Br2N.

 

ʻAno:

ʻO 2-pyridinamine, 5,6-dibromo-he paʻa ʻole i ka melemele ʻeleʻele. Paʻa ia ma ka lumi wela, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik, e like me nā ʻona a me nā eter, a hiki ke hoʻoheheʻe iki ʻia i ka wai. Loaʻa iā ia nā waiwai amino a me pyridine ikaika.

 

E hoʻohana:

2-pyridinamine, 5,6-dibromo-hiki ke hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik. Hoʻohana ʻia ia i ka synthesis lāʻau, synthesis pesticide a me ka synthesis dye.

 

Kaʻina hoʻomākaukau:

2-pyridinamine, 5,6-dibromo-hiki ke hoʻomākaukau ʻia e nā ʻano hana synthetic. ʻO kahi ala maʻamau ka hoʻolauna ʻana i ka pūʻulu amino ma ke kumu o ka nitrate a i ʻole amino substitution o 2,3-dibromopyridine.

 

ʻIke palekana:

ʻAʻole i hōʻike maopopo ʻia nā ʻike palekana kūikawā no 2-pyridinamine, 5,6-dibromo. Eia nō naʻe, ma ke ʻano he hui kūlohelohe, pono e mālama ʻia nā hana pale kūpono i ka wā e lawelawe ai, e like me ke komo ʻana i nā mīkina lima, nā maka maka maka a me nā lole pale, a me ka pale ʻana i ka pili ʻana me ka ʻili a me nā maka. Eia kekahi, pono e hana ʻia i loko o kahi kaiapuni maikaʻi e pale aku ai i ka inhalation o kona mau mahu a lepo paha. Ma mua o ka hoʻohana ʻana, ʻoi aku ka maikaʻi e nīnau i ka pepa ʻikepili palekana kūpono a i ʻole e nīnau i kahi loea.
