Hoʻolauna
He pūhui mea ola ia me ke kumu hoʻohālike kemika C7H7N2O3. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:
ʻAno:
-Nani: He aniani melemele a pauda paha.
-Solubility: Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, chloroform a me dimethyl sulfoxide.
-Ka helu hoʻoheheʻe: ʻO kona helu heheʻe ma kahi o 135-137 degere Celsius.
-Nā waiwai kemika: He pūhui ʻala i loko o ka nitrogen me kekahi hana hoʻololi kemika.
E hoʻohana:
-Hiki ke hoʻohana ʻia ma ke ʻano he waena no ka synthesis o nā pūhui organik ʻē aʻe.
-Hiki ke hoʻohana ʻia e like me ka mea maka no nā pesticides a me nā herbicides i ka māla mahiʻai.
Hanana:
-hiki ke hoʻomākaukau ʻia ma ka hana ʻana i ka 2-methylpyridine me ka waikawa nitric. Penei nā ʻanuʻu kikoʻī: ka hoʻoheheʻe ʻana i ka 2-methylpyridine i loko o ka ethanol, hoʻohui i ka waikawa nitric concentrated, a loaʻa ka huahana ma o ka crystallization ma hope o ka hopena.
ʻIke palekana:
-Maikaʻi loa i ka pili ʻana me ka ʻili, inhalation a i ʻole ma hope o ka ʻai ʻana.
-E pale i ka pili ʻana i ka ʻili a me ka inhalation ke pili. E hoʻohana i nā maka aniani a me nā mīkina lima inā pono.
-E nānā i nā kaʻina hana palekana i ka wā o ka lawelawe ʻana a me ka mālama ʻana a hoʻopaʻa pono.
-inā pono, e nānā i ka Pepa ʻIkepili Palekana Kemika (MSDS) no ka ʻike kikoʻī palekana.
