Description

1,4-Icosanediol CAS NO 16274-31-0 is a long-chain aliphatic diol, a high-purity chemical building block characterized by its 20-carbon backbone with terminal hydroxyl groups. This molecular structure makes it a valuable intermediate for synthesizing specialized polymers, surfactants, and lubricants where specific chain length and bifunctionality are critical. It is essential for R&D and production in the advanced materials, specialty chemicals, and pharmaceutical intermediates sectors.

Application

• Polymer Synthesis: Key monomer for producing high-performance polyesters and polyurethanes, imparting flexibility and specific physical properties.
• Specialty Surfactants & Emulsifiers: Serves as a hydrophobic spacer in the synthesis of non-ionic surfactants for demanding industrial formulations.
• Lubricant & Grease Additives: Used to create synthetic ester bases and viscosity modifiers for high-temperature lubricants.
• Pharmaceutical & Cosmetic Intermediates: Building block for synthesizing long-chain derivatives used in drug delivery systems and personal care actives.
• Macromolecular Initiators/Coupling Agents: Utilized in controlled polymerization techniques and as a chain extender in polymer networks.
• Research & Development: Critical reference standard and starting material in organic chemistry and materials science research.
