3-Aminophthalic acid is a product of the oxidation of luminol. The reaction requires the presence of a catalyst. A mixture of luminol and hydrogen peroxide is used in forensics. When the mixture is sprayed on an area that contains blood, the iron in the hemoglobin in the blood catalyzes a reaction between the mixture, resulting in 3-aminophthalate which gives out light by chemiluminescence.[1]
