| Nā hōʻailona pōʻino | Xi – Hoʻohaunaele |
| Nā Code Risk | 36/37/38 – Hoʻonanea i nā maka, ʻōnaehana hanu a me ka ʻili. |
| Ka wehewehe palekana | S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S36 – E komo i nā lole pale kūpono. |
Hoʻolauna
ʻO ka 2-methyll-5-nitropyridine he mea hoʻohuihui mea ola me ke kumu kemika C6H6N2O2, nona nā waiwai penei:
1. Nani: colorless to light yellow crystal;
2. Aʻala: ʻaʻohe ʻala kūikawā;
3. Lae hehee: 101-104 degere Celsius;
4. Solubility: aneane hiki'ole ke ho'ohehe'e 'ia i ka wai, hiki ke ho'ohehe'e 'ia e like me ka ethanol a me ka dichloromethane.
Hoʻohana nui ʻia ka 2-Methyl-5-nitropyridine ma ke ʻano he mea maka a me ka waena i ka synthesis organik a me ka ʻoihana lāʻau. Hiki ke hoʻohana ʻia no ka synthesis o pyridine a me thiophene pūhui, a hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā lāʻau pesticides, nā mea hoʻonaninani a me kekahi mau mea hoʻohui i ka lāʻau lapaʻau.
ʻO ka hoʻomākaukau ʻana i ka 2-methyll-5-nitropyridine hiki ke hana ʻia e nā pae aʻe:
Hoʻopili ʻia ka 1.2-pyridine acetic acid a me ka sodium nitrite ma lalo o nā kūlana acidic e hana i ka 2-nitropyridine.
2. ʻO ka hopena o ka 2-Nitro pyridine me ka methylating reagent (e like me ka methyl iodide) e hana i ka 2-Methyl-5-nitropyridine.
I ka hoʻohana ʻana a mālama ʻana i ka 2-methyll-5-nitropyridine, pono ʻoe e hoʻolohe i kēia ʻike palekana:
-He mea puhi ia, e pale i ka pili me ke ahi;
-E hoʻolohe i nā hana pale i ka wā o ka hana, e like me ke komo ʻana i nā aniani pale a me nā mīkina lima;
-e pale i ka inhalation o kona kinoea a lepo paha, e pale i ka pili o ka ili;
- E kūʻai i loko o kahi pahu i pani ʻia, ma kahi mamao o ke ahi a me nā mea hoʻoneʻe;
-E hōʻalo i ka hui ʻana me nā oxidants ikaika a i ʻole nā waikawa ikaika.
