Rhodium trichloride is widely used as a catalyst in various organic synthesis reactions, particularly in hydrogenation and carbonylation processes. It plays a crucial role in the production of fine chemicals and pharmaceuticals, enabling efficient and selective transformations. Additionally, it is employed in the manufacturing of specialty coatings and materials, where its catalytic properties enhance performance and durability. In electroplating, rhodium trichloride is utilized to deposit thin, corrosion-resistant rhodium layers on surfaces, improving their appearance and longevity. It also finds application in research and development for studying catalytic mechanisms and exploring new chemical pathways.
