ʻO ia ka mea hoʻohui kino me ke ʻano kemika C8H8N2O3.Nature:
-He paʻa keʻokeʻo keʻokeʻo ka helehelena.
-ʻO ka helu heheʻe ma kahi o 43-47°C.
-Stable i ka lumi wela, akā pili i ka malamalama a me ka wela.
-Soluble i nā mea hoʻoheheʻe organik e like me ka ethanol, ether a me ka chloroform, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
-he mea koʻikoʻi koʻikoʻi koʻikoʻi synthesis intermediate, hoʻohana nui ʻia i ka hoʻomākaukau ʻana i nā pūhui ʻē aʻe, e like me nā pesticides, pharmaceuticals a me nā mea hoʻonaninani.
-Ma ke kahua o ka lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize i nā mea antibacterial, nā lāʻau anti-inflammatory a me nā lāʻau anti-cancer.

Hanana:
-ʻO ke ʻano hoʻomākaukau maʻamau ʻo ka hana ʻana i ka 4-methylpyridine me ka nitrosamine e hoʻohua ai i ka 4-nitroso-2-methylpyridine, a laila e hoʻopili me ka methanol e hana ai.

ʻIke palekana:
-he pūhui nitro organik, he mea weliweli. Hiki i ka hoʻopili ʻana me nā maka, ka ʻili a i ʻole ka inhalation o kona lepo ke kumu i ka huhū a me nā hopena maʻi.
- Pono ka hoʻohana ʻana i nā lako pale pilikino kūpono a e hana i loko o kahi kaiapuni maikaʻi. E hōʻalo i ka hanu ʻana i kāna kinoea, lepo a i ʻole ka hopena a pale aku i ka pili ʻana me ka ʻili ʻole.
-E nānā i nā kaʻina hana palekana i ka wā o ka mālama ʻana a me ka mālama ʻana i mea e pale ai i ka hoʻā ʻana a me ke kūkulu ʻana. Pono e mālama ʻia i loko o kahi pahu paʻa, ma kahi mamao o nā mea hiki ke ahi a me nā mea hoʻoneʻe.
