Description

Dimethyl Undecanedioate is a high-purity diester compound, also known as dimethyl undecanedioate CAS NO 4567-98-0. It serves as a versatile and valuable chemical intermediate for the synthesis of polymers, fragrances, and specialty chemicals. This product is essential for manufacturers in the pharmaceutical, cosmetic, and advanced materials industries seeking reliable building blocks for complex molecules.

Application

• Polymer & Plasticizer Intermediate: A key monomer for the production of polyesters, polyamides (nylon-11,12), and specialty plasticizers, contributing to material flexibility and durability.
• Fragrance & Flavor Synthesis: Used in the manufacture of macrocyclic musk fragrances and other aroma chemicals due to its long-chain diacid derivative properties.
• Pharmaceutical Intermediates: Acts as a precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems.
• Lubricant & Grease Additive: Employed in formulating synthetic lubricants and high-performance greases for industrial applications.
• Corrosion Inhibitor Precursor: Used to develop long-chain derivatives that function as effective corrosion inhibitors in metalworking fluids and coatings.
• Specialty Surfactant Production: Serves as a starting material for synthesizing biodegradable, non-ionic surfactants and emulsifiers.
