1,1′-[(phenylmethylene) bis[(2-methoxy-4,1-phenyl)azo]]di-2-naphthol, yomwe imadziwikanso kuti AO60, ndi utoto wopangidwa ndi organic. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

Katundu: AO60 ndi wachikasu mpaka kufiira-bulauni crystalline ufa, wosasungunuka m'madzi, sungunuka mu zosungunulira organic monga methanol, ethanol ndi chloroform. Ndiwokhazikika mu acidic, ndale komanso zamchere.

Ntchito: AO60 imagwiritsidwa ntchito makamaka ngati utoto ndi chizindikiro. Itha kugwiritsidwa ntchito ngati chopangira utoto pazovala, makamaka pakupaka utoto wa ulusi wachilengedwe monga thonje ndi bafuta. Itha kugwiritsidwanso ntchito popaka utoto mapulasitiki ndi mphira. Amagwiritsidwanso ntchito ngati chizindikiro cha acid-base komanso kudziwa pH.

Njira yokonzekera: Kukonzekera kwa AO60 nthawi zambiri kumapezedwa pophatikizana kwa nitrous acid ndi styrene, kenako ndikuchita ndi 2-naphthol kupanga chandamale.
