11-Aminoundecanoic acid, also known as 11-AUA or 11-aminoundecanoate, has several commercial uses, primarily in the production of nylon and polyamide resins. Here are some of its main commercial applications:

Nylon 11 Production

11-Aminoundecanoic acid is a key precursor in the synthesis of nylon 11, a type of polyamide commonly used in the production of engineering plastics, fibers, and specialty materials. Nylon 11 exhibits excellent mechanical properties, chemical resistance, and thermal stability, making it suitable for various applications, including automotive components, electrical connectors, and industrial equipment.

Polyamide Resins

Besides nylon 11, 11-aminoundecanoic acid can be utilized in the synthesis of other polyamide resins and copolymers. These resins find applications in coatings, adhesives, sealants, and molding compounds, where properties such as toughness, flexibility, and chemical resistance are desired.

Adhesives and Sealants

Polyamide resins derived from 11-aminoundecanoic acid are used as components in the formulation of adhesives and sealants. These products offer excellent adhesion to a wide range of substrates, including metals, plastics, and composites, making them suitable for bonding and sealing applications in construction, automotive, and aerospace industries.

Coatings and Paints

Polyamide-based coatings and paints, synthesized from 11-aminoundecanoic acid, are employed in various industrial and architectural applications. These coatings provide durable and protective finishes with excellent adhesion, abrasion resistance, and chemical resistance, making them suitable for use in corrosion protection, flooring, marine, and decorative coatings.

Textile Fibers

Nylon 11 fibers, produced from 11-aminoundecanoic acid, are utilized in the manufacture of specialty textiles and industrial fibers. These fibers offer high strength, abrasion resistance, and dimensional stability, making them suitable for applications such as ropes, nets, brushes, and technical textiles.

Biomedical Applications

Some research suggests potential biomedical applications for 11-aminoundecanoic acid derivatives, such as drug delivery systems and biomaterials. However, these applications are still in the early stages of development and require further research and testing for commercialization.
