The global N,N’-Diiodo-5,5-dimethylhydantoin market size was valued at USD 45.2 million in 2022. The market is projected to grow from USD 48.1 million in 2023 to USD 72.5 million by 2028, exhibiting a CAGR of 8.5% during the forecast period.

N,N’-Diiodo-5,5-dimethylhydantoin (DIH) is a versatile organic compound known for its powerful oxidizing properties. This white to off-white crystalline powder is synthesized from 5,5-dimethylhydantoin and iodine, resulting in a stable reagent that releases iodine under mild conditions. Its key attributes include high reactivity, selectivity in organic transformations, and safety compared to elemental iodine, making it invaluable in fine chemical synthesis across pharmaceuticals, agrochemicals, and specialty materials production.

The market for DIH remains specialized yet essential, driven by the escalating need for efficient iodination and oxidation agents in drug development, crop protection formulations, and advanced imaging technologies. As regulatory pressures mount for greener chemical processes, DIH’s eco-friendly profile—releasing hypoiodous acid rather than free iodine—positions it for sustained growth amid global sustainability initiatives.
