- Thepa ea 'Mele le Lik'hemik'hale: NTA e na le boima ba molek'hule ea 244.16 g/mol le ntlha e qhibilihang ke 352-358°C. E na le ho qhibiliha ho hoholo ha metsoako ea tlhaho e kang chloroform, ethyl acetate, le benzene.Ho phaella moo, e bontša botsitso bo botle tlas'a maemo a tloaelehileng, ho lumella ho boloka le ho tsamaisa ntle le ho senyeha ho hoholo.

- Likopo: NTA e fumana ts'ebeliso liindastering tse fapaneng, ho kenyeletsoa tsa meriana, lidae le lipolasetiki.Lefapheng la meriana, e sebetsa e le setsi sa bohlokoa ho kopanngoeng le litlhare, e kenyang letsoho ntlafatsong ea liphekolo tse ncha.Reactivity ea eona e phahameng le ho lumellana ho etsa hore e be karolo e loketseng tlhahisong ea lidae tse sebetsang hantle, tse fanang ka thepa ea mebala e ikhethang.Ho feta moo, NTA e sebelisoa e le monoma ha ho etsoa li-polymers tse khethehileng le li-resin, e ntlafatsang ts'ebetso ea tsona ka kakaretso le ho tšoarella.
