  • Applications

    1,3-Bis(2-hydroxyethyl)-5,5-dimethyl-2,4-imidazolidinedione (CAS 26850-24-8) is a diol-containing hydantoin derivative used primarily as an intermediate in the synthesis of specialty chemicals and functional materials. In practice, it is often employed as a diol or crosslinking component in polymer formulations and resins, contributing to increased crosslink density and thermal stability in coatings, adhesives, and inks. Owing to its two hydroxyl groups and the hydantoin core, the compound may also act as a chelating/complexing agent for metal ions in electronics-related formulations or metal finishing processes. Additionally, it serves as a synthetic building block for functional hydantoin derivatives used in specialty chemicals, and is commonly evaluated as a precursor for polymer and material applications in electronics, coatings, and related industries.
