ʻO ka 4-Methylamino-3-nitrobenzoic acid he mea hoʻohuihui. Eia ka ʻike e pili ana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka palekana o kēia pūhui:

 

ʻAno maikaʻi:

- ʻO ka 4-Methylamino-3-nitrobenzoic acid he aniani melemele ʻole a ʻulaʻula me ka beaker a me ka ʻono ʻawaʻawa.

- Hiki ke hoʻoheheʻe ʻia ka hui i loko o ka wai a hiki ke hoʻoheheʻe ʻia i ka ethanol a me nā mea hoʻoheheʻe etera.

 

E hoʻohana:

- Hoʻohana maʻamau ia i ka hoʻomākaukau ʻana i nā mea kemika e like me nā mea pena, nā pesticides, a me nā mea pahū.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 4-Methylamino-3-nitrobenzoic acid e ka acylation o ka p-nitrobenzoic acid a me toluidine.

- I ka hopena, ua hoʻohui mua ʻia ka nitrobenzoic acid a me ka toluidine i ka moku pane, a hoʻoulu ʻia ka hopena i ka wela kūpono e loaʻa ai ka huahana.

 

ʻIke palekana:

- ʻO ka 4-Methylamino-3-nitrobenzoic acid he mea hoʻonāukiuki a pono e mālama ʻia me ka akahele a pono e hoʻohana i nā mea pale pilikino.

- Pono e mālama i ka wā e lawelawe ai i ka pūhui e pale aku i ka pili ʻana me ka ʻili a me nā maka, a e pale aku i ka hanu ʻana i kona lepo a i ʻole ka mahu.

- E mālama ʻia mai ke ahi a me nā kumu wela a paʻa paʻa i nā ipu.

- E mālama pono i nā kaʻina hana palekana i ka wā e hoʻohana ai. E like me nā hana kōkua mua a me nā ʻano hoʻolei ʻōpala.

- Inā loaʻa iā ʻoe kekahi ʻeha a i ʻole inhale nui o ka hui, e ʻimi koke i ka lāʻau lapaʻau.
