ʻO ka 4-Amino-2-fluorobenzoic acid he mea hoʻohuihui.

 

Hoʻohana nui ʻia ka 4-Amino-2-fluorobenzoic acid i ke kula o ka synthesis organik.

 

Hoʻomākaukau ʻia ka 4-amino-2-fluorobenzoic acid ma ka hana ʻana i ka 2-fluorotoluene me ka amonia. Hiki ke hoʻololi i keʻano hoʻomākaukau kūikawā e like me nā pono a me nā kūlana kūikawā.

 

I ka hoʻohana ʻana i ka 4-amino-2-fluorobenzoic acid, pono e hoʻomanaʻo ʻia kēia mau ʻōlelo palekana:

 

Hōʻalo i ka pili ʻana me ka ʻili a me nā maka. Pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima, nā maka aniani, a me nā mea ʻē aʻe ke hoʻohana ʻia.

 

E hō'ole i ka ho'ohu 'ana i kona kinoea a i 'ole ka lepo, a pono e hana ma kahi e ho'ohehe'e 'ia.

 

I ka wā e mālama ai, pono e waiho ʻia ma kahi maloʻo, ʻoluʻolu, a me ka ea, kahi mamao mai nā lapalapa a me nā kumu wela.

 

Ma mua o ka hoʻohana ʻana, pono ʻoe e hoʻomaopopo i kona palekana a me ka mālama ʻana i ka hana i nā kikoʻī, a hana e like me nā lula pili.
