Used in specialized organic synthesis as a catalyst for nitration reactions, particularly in the preparation of polynitro compounds. Its unique coordination structure enhances selectivity in aromatic nitration, making it valuable in the development of energetic materials and pharmaceutical intermediates. Also investigated for potential use in controlled-release ammoniation processes due to its ammonia-labile ligands. Handling requires caution due to the presence of nitro groups and platinum metal, which can pose stability and toxicity concerns.
