Used as a catalyst in organic synthesis reactions, particularly in esterification and oxidation processes. Employed in the preparation of praseodymium-doped materials for use in specialty glasses and ceramics that exhibit enhanced optical properties, such as durable yellow-green coloration. Popular in artistic and decorative applications requiring specific color shades. Serves as a precursor in the production of phosphors for lamps and display technologies. Applied in research settings for luminescent labeling and as a source of Pr³⁺ ions in coordination chemistry studies. Also utilized in the development of magnetic materials due to its paramagnetic characteristics. Additionally, used in laboratory studies to investigate the behavior of rare earth metals in the form of acetate salts.
