Description and Uses
9-Anthracenecarboxylic acid (9-AC) is a yellow powder with excellent light stability and fluorescence properties, which can be used as a dye intermediate. The binding constant for fluorescein and 9-AC is 982 M−1, while it is only 81 M−1 for the eosin ester and 9-AC. The fluorescence spectrum of 9-AC in ethanol exhibits strong concentration dependence. At concentrations below 10-5 mol/l, the spectrum displays an anthracene-like structure, whereas above 10-3 mol/l, the spectrum shifts towards the red region, transforming into a broad, structureless band. Furthermore, 9-AC may serve as an electron-transfer ligand for applications in semiconductor or OLED fields.
Anthracene-9-carboxylic acid is a Cl- transport inhibitor with a moderate to strong inhibitory action on PKA activated cardiac IcI.
