Beschreibung
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.
Chemische Eigenschaften
yellow powder
Verwenden
Anthracene-9-carboxylic acid is a Cl- transport inhibitor with a moderate to strong inhibitory action on PKA activated cardiac IcI.
Definition
ChEBI: An anthroic acid carrying the carboxy substituent at position 9.
Application
9-Anthracenecarboxylic acid (9-AC) is a dye with fluorescent properties and can be used for the quantitative analysis of cationic surfactants. This method is based on the interaction between 9-AC and cationic surfactants and the formation of non-fluorescent ion-binding complexes. The addition of a trace amount of cationic surfactant reduced the fluorescence intensity of 9-AC. Under optimum conditions, the ratio of fluorescence intensity in the absence and presence of cationic surfactants was proportional to the concentration of cationic surfac tants.
