Description

1,4-Octanediol CAS NO 51916-47-3 is a linear aliphatic diol characterized by its two terminal hydroxyl groups separated by a six-carbon chain. This specific molecular structure makes it a valuable bifunctional building block for polymerization and organic synthesis. It is primarily sought after by manufacturers in the polymer, specialty chemical, and pharmaceutical intermediate sectors for creating tailored materials with specific properties.

Application

• Polymer Synthesis: Serves as a chain extender or monomer in the production of polyurethanes, polyesters, and other specialty polymers, influencing flexibility and crystallinity.
• Pharmaceutical Intermediates: Used as a key raw material in the synthesis of active pharmaceutical ingredients (APIs) and other complex organic molecules.
• Liquid Crystal Production: Acts as a spacer or terminal group in the synthesis of liquid crystal compounds for display technologies.
• Cosmetic and Personal Care Ingredients: Utilized in the formulation of emollients, humectants, and as a precursor for esters in fragrances and skin care products.
• Plasticizers and Additives: Functions as an intermediate for producing plasticizers that enhance the flexibility of PVC and other plastics.
• Cross-linking Agent: Employed in coatings, adhesives, and resin systems to improve hardness, chemical resistance, and thermal stability.
• Organic Synthesis: A versatile reagent for constructing carbon chains and introducing hydroxyl functionality in fine chemical manufacturing.
