Description

2,2-Dichlorooctadecanoic Acid is a high-purity, long-chain chlorinated fatty acid derivative. This compound serves as a valuable synthetic intermediate and building block in advanced organic synthesis, offering unique reactivity due to the geminal dichloro substitution on the alpha carbon. It is primarily utilized by research and development chemists in the pharmaceutical, agrochemical, and specialty chemical industries for the synthesis of complex molecules, surfactants, and functional materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipophilic side chains or specific stereochemistry.
• Agrochemical Synthesis: Serves as a key precursor for manufacturing herbicides, fungicides, and plant growth regulators with modified activity profiles.
• Specialty Surfactants & Lubricant Additives: Acts as a starting material for producing anionic surfactants and extreme pressure (EP) additives for industrial lubricants.
• Polymer Science: Employed as a monomer or co-monomer in the production of specialty polyesters and polyamides with enhanced properties.
• Organic Synthesis Building Block: Utilized in nucleophilic substitution and elimination reactions to introduce long alkyl chains with reactive handles.
• Material Science Research: Investigated for creating self-assembled monolayers (SAMs) and other advanced functional materials.
