9,10-Anthracenediyl-bis(methylene)dimalonic acid

Description

9,10-Anthracenediyl-bis methylene dimalonic acid ABMDMA is a biological dye and indicator used to detect singlet oxygen generation SOG . 9,10-Anthracenediyl-bis methylene dimalonic acid is water-soluble derivative of anthracene. 9,10-Anthracenediyl-bis methylene dimalonic acid can be photobleached by singlet oxygen to its corresponding endoperoxide. This reaction can be monitored spectrophotometrically by recording the decrease of absorbance at 400 nm.
