The 3‐aminophthalic acid anion is a light emitter in luminol chemiluminescence. In the present study, the chemiluminescence of the 3‐aminophthalic acid anion itself in the presence of hydrogen peroxide–cobalt (II) was studied. The results indicated that 3‐aminophthalic acid anion is highly chemiluminescent in the typical hydrogen peroxide–cobalt (II) system. The peak wavelength of this chemiluminescence and the kinetic profile of the 3‐aminophthalic acid anion–hydrogen peroxide–cobalt (II) reaction showed similarity with that of luminol, but the chemiluminescence of 3‐aminophthalic acid anion had a much lower background signal. In addition, the chemiluminescence mechanism of 3‐aminophthalic acid anion–hydrogen peroxide–cobalt (II) was also discussed and speculated as the interaction between 3‐aminophthalic acid anion and singlet oxygen.
