13-Hydroxytridecanoic acid is primarily used in the synthesis of specialized polymers and resins. Its hydroxyl group allows it to act as a building block in creating polyesters and polyamides, which are essential in producing high-performance materials. These materials find applications in coatings, adhesives, and industrial plastics, offering enhanced durability and chemical resistance. Additionally, it serves as an intermediate in the production of surfactants and lubricants, contributing to improved formulation stability and performance in various industrial processes. Its role in organic synthesis also extends to the development of bioactive compounds, particularly in pharmaceutical research, where it aids in creating molecules with potential therapeutic properties.
