Description

Undecane-1,4-Diol CAS NO 4272-02-0 is a high-purity, long-chain aliphatic diol characterized by its two hydroxyl groups positioned at the 1 and 4 carbon atoms. This specific molecular structure makes it a valuable bifunctional building block for polymerization and organic synthesis, offering a unique balance of hydrophobicity and reactivity. It is primarily utilized by R&D chemists and process engineers in the specialty polymer, pharmaceutical intermediate, and advanced material sectors.

Application

• Polymer Synthesis: Serves as a chain extender or monomer in the production of specialty polyurethanes, polyesters, and polycarbonates, imparting flexibility and specific physical properties.
• Pharmaceutical Intermediates: Used as a key synthon in the multi-step synthesis of complex active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Lubricant & Plasticizer Additives: Functions as a precursor or intermediate for synthesizing high-performance ester-based lubricants and specialty plasticizers.
• Surface Coatings & Resins: Incorporated into alkyd resins and other coating formulations to modify curing characteristics, adhesion, and durability.
• Cosmetic & Personal Care Ingredients: Acts as an intermediate for producing emollients, surfactants, and viscosity modifiers in advanced formulations.
• Cross-linking Agent: Utilized in thermosetting resins and elastomers to control cross-link density and final material performance.
• Chemical Research (R&D): Employed as a standard or building block in organic chemistry research and method development.
