Description

11-Chloro-Undecanoic Acid is a versatile, medium-chain fatty acid derivative featuring a terminal chloro group. This functionalized building block is critical for the synthesis of specialized surfactants, lubricant additives, and pharmaceutical intermediates. It is particularly valuable for researchers and manufacturers in the fine chemical, polymer, and agrochemical industries seeking to introduce specific hydrophobic and reactive functionalities into their products.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the production of active pharmaceutical ingredients (APIs) and prodrugs, leveraging the reactive chloro group for further functionalization.
• Surfactant & Detergent Synthesis: Used to manufacture specialized anionic and nonionic surfactants with unique chain lengths for industrial and institutional cleaning formulations.
• Polymer & Resin Modifier: Acts as a monomer or co-monomer in polycondensation reactions to create polyesters and polyamides with modified properties like flexibility and hydrophobicity.
• Lubricant & Grease Additive: Employed in the synthesis of ester-based lubricants and metalworking fluids, where it contributes to stability and performance characteristics.
• Agrochemical Intermediate: Utilized in the production of herbicides, fungicides, and plant growth regulators that require specific aliphatic chain structures.
• Organic Synthesis Building Block: A valuable reagent in organic chemistry for carbon chain elongation and the introduction of carboxylic acid functionality via further reactions of the chloro group.
• Corrosion Inhibitor Precursor: Used to develop long-chain fatty acid-based inhibitors for protecting metals in various industrial processes.
