1,11-Undecanedicarboxylic acid Cas 505-52-2

High-performance nylon/polyamide monomers: Core raw materials for long-chain nylons (such as Nylon 1211 and Nylon 1111) used in fuel lines, precision gears, and cable sheathing.
Raw materials for polyester and polyurethane synthesis: Used to synthesize long-chain polyesters and polyester polyols that enhance resin flexibility and weather resistance; also serve as polyurethane chain extenders to improve elasticity and low-temperature toughness.
Additives for lubricants and metalworking fluids: Used to produce dicarboxylate synthetic base oils, offering stable lubrication across a wide temperature range, as well as excellent rust prevention and anti-wear properties.
Fine chemical intermediates: Used in the synthesis of fragrances, metal chelating agents, and coating curing agents; also utilized in the production of hot-melt adhesives and polyester resins for powder coatings.
