Acid ke motsoako oa organic o nang le foromo ea lik'hemik'hale C7H7NO2. Ke kristale e tiileng e se nang 'mala, e qhibilihang ka metsing le ka har'a metsoako ea tlhaho.

 

Acid e na le lisebelisoa tse fapaneng. E ka sebelisoa e le motsoako oa motsoako oa organic bakeng sa ho lokisa metsoako e meng. E ka sebetsa joalo ka ligand bakeng sa li-organometallic complexes le ho nka karolo ho karabelo ea catalytic. Ho phaella moo, e ka boela ea sebelisoa ha ho etsoa litlhare tse itseng.

 

Ho na le mekhoa e mengata ea ho lokisa ICT. Mokhoa o mong o tloaelehileng ke ho kopanya ka kalafo le oxidation ea toluene. Ka ho khetheha, toluene e qala ho itšoara ka acetaldehyde ka pel'a moemeli oa oxidizing ho hlahisa 3-methyl-4-picolinic acid ester, e ntan'o kenngoa ho acid hydrolysis ho fumana sehlahisoa se lebisitsoeng.

 

Tšireletseho ea asiti e holimo, empa litaba tse ling tsa polokeho li ntse li hloka ho eloa hloko. Apara lisebelisoa tse nepahetseng tsa ts'ireletso tse kang likhalase le liatlana nakong ea ts'ebetso. Qoba ho hema lerōle le khase tse hlahisoang 'me u qobe ho kopana le letlalo. Nakong ea polokelo le lipalangoang, tlhokomelo e lokela ho lefshoa ho mehato e thibelang mongobo, e thibelang mollo le mehato e thibelang ho phatloha. Haeba motho a ka ja ka phoso kapa a kopana, batla keletso ea bongaka hang-hang 'me u tlise leqephe la polokeho ea sehlahisoa sena sepetlele.
