Sigma-Aldrich 9,10-Anthracenediyl-bis(methylene)dimalonic acid. BioReagent, suitable for fluorescence, ≥90% (HPCE). 50 mg

9,10-Anthracenediyl-bis(methylene)dimalonic acid or ABDA is a singlet oxygen probe.[1] It is highly fluorescent and soluble in water and binds to lipopolysaccharides (LPS) found in the cell membrane. 9,10-Anthracenediyl-bis(methylene)dimalonic acid takes four negative charges upon fully deprotonation in neutral aqueous solutions, stabilizing the ion-pair complex and facilitating selective recognition of LPS over other common ionic species of clinical significance. In addition to the emission maximum at 407 nm, there are lower maxima at 431, 457, and 485 nm.

9,10-Anthracenediyl-bis(methylene)dimalonic acid is widely used as a singlet oxygen detector probe. [1] 9,10-Anthracenediyl-bis(methylene)dimalonic acid is suitable for assessing the photodynamic effect of curcumin Vibrio parahaemolyticus, which is a significant cause of bacterial diarrhea.[2]
