1,3-Bis(3-hydroxypropyl)urea is commonly used in the synthesis of polymers and resins, particularly in the production of polyurethane foams and coatings. Its bifunctional structure, containing both hydroxyl and urea groups, makes it a valuable crosslinking agent, enhancing the mechanical properties and durability of the final materials. It is also employed in the formulation of adhesives and sealants, where it improves adhesion strength and flexibility. Additionally, this compound finds applications in personal care products, such as hair and skin conditioning agents, due to its moisturizing and stabilizing properties. In the pharmaceutical industry, it is utilized as an intermediate in the synthesis of active ingredients and drug delivery systems.
