This chemical is primarily utilized as a ligand in catalytic processes, particularly in transition metal catalysis. It plays a crucial role in facilitating various organic transformations, such as cross-coupling reactions, hydrogenation, and hydroformylation. Its sterically demanding structure, due to the di-tert-butyl groups, enhances selectivity and efficiency in these reactions. Additionally, it is employed in the synthesis of fine chemicals and pharmaceuticals, where precise control over reaction pathways is essential. The hydrochloride form ensures stability and ease of handling in laboratory and industrial settings.
