1,12-Dodecanediol (DCO)

1,12-Dodecanediol is a linear aliphatic diol characterized by its twelve-carbon chain and terminal hydroxyl groups. This crystalline solid is recognized for its utility as a high-performance chemical intermediate in polymer chemistry and specialty lubricant formulations. Known by its CAS registry number 5675-51-4, it serves as a critical monomer for synthesizing high-grade polyesters, polyurethanes, and polycarbonate diols. The extended methylene bridge provides a unique combination of hydrophobicity and flexibility to derived materials, making it indispensable for engineering plastics. Its structural regularity facilitates the production of semicrystalline polymers with improved thermal stability and moisture resistance compared to shorter-chain analogs. Furthermore, 1,12-dodecanediol is employed in the manufacturing of cosmetics and pharmaceutical delivery systems, where its biocompatibility and structural integrity are valued. As industries transition toward durable, high-performance materials, this long-chain diol remains a cornerstone for developing resilient coatings, adhesives, and advanced elastomers, providing superior mechanical properties and chemical resistance in demanding industrial environments.
