Bis(2,6-diisopropylphenyl)carbodiimide is widely used as a stabilizer in polyurethane and polyurea systems. It effectively prevents the degradation of these materials by reacting with water or moisture, which can otherwise lead to hydrolysis and loss of mechanical properties. This makes it particularly valuable in coatings, adhesives, and elastomers exposed to humid or wet environments. Additionally, it is employed in the synthesis of pharmaceuticals and agrochemicals, where it acts as a coupling agent to facilitate the formation of peptide bonds or other complex molecular structures. Its ability to scavenge isocyanates also makes it useful in controlling the reactivity and shelf life of polyurethane precursors.
