Product Information
Description: 9,10-Anthracenediyl-bis(methylene)dimalonic acid (ABDA) is a biological dye and indicator used to detect singlet oxygen generation (SOG). 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.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
