  • Applications

    11-Aminoundecanoic acid (CAS 2432-99-7) is primarily used as a monomer to synthesize nylon-11 (polyamide-11), a high-performance polymer with good flexibility and chemical resistance; it also serves in the production of related polyamide resins for coatings and adhesives used in industrial hardware; nylon-11 and its derivatives find applications in tubing, hoses, films, and electrical insulation due to toughness and moisture resistance; it can be used to prepare specialty polymers employed in automotive and aerospace components; and it may be used to formulate medical-grade polyamides for certain medical devices.
