9-Anthracenepropionic Acid丨CAS 41034-83-7

9-Anthracenepropionic acid (CAS 41034-83-7) is an anthracene-based aromatic carboxylic acid widely used in fluorescent labeling, organic synthesis, and material science. In biochemical research, it is applied as a fluorescent probe or tagging agent due to the intrinsic fluorescence of the anthracene moiety, enabling studies of biomolecules, cellular imaging, and photophysical analysis. In organic synthesis, it serves as a versatile intermediate for preparing anthracene derivatives, esters, amides, and polymerizable monomers. It is also used in the development of optoelectronic materials, organic light-emitting diodes (OLEDs), and other photonic applications, where its rigid aromatic structure and photostability enhance performance.

The benefits of 9-anthracenepropionic acid stem from its strong fluorescence, structural rigidity, and functional versatility. The anthracene core provides high quantum yield, photostability, and planarity, making it ideal for fluorescent tagging and optical applications. The propionic acid group offers a reactive site for esterification, amidation, and conjugation reactions, enabling attachment to biomolecules, polymers, or other functional scaffolds. Its combination of a fluorescent aromatic core and reactive carboxyl group allows efficient synthesis of functional derivatives while maintaining photophysical properties, supporting both analytical and material applications.
