Description

Pentadecane-1,3-Diol is a high-purity, long-chain aliphatic diol with the CAS registry number 66271-79-2. This compound is valued for its dual hydroxyl functionality and hydrophobic carbon chain, making it a versatile intermediate for specialty synthesis. It is primarily sought by R&D and production teams in the cosmetics, pharmaceuticals, and polymer industries for creating advanced materials with tailored properties.

Application

• Cosmetic & Personal Care Ingredient: Serves as a key building block for synthesizing high-performance emollients, moisturizers, and viscosity modifiers in creams and lotions.
• Pharmaceutical Intermediate: Used in the research and development of prodrugs, lipophilic drug carriers, and controlled-release formulations.
• Polymer & Resin Modifier: Acts as a monomer or chain extender in polyurethane and polyester systems to enhance flexibility, hydrophobicity, and chemical resistance.
• Lubricant & Grease Additive: Employed in the synthesis of specialty esters that function as synthetic lubricant base stocks or performance additives.
• Surfactant & Detergent Synthesis: Provides a long hydrophobic backbone for creating non-ionic surfactants with specific solubility and surface activity profiles.
• Flavor & Fragrance Carrier: Utilized as a solvent or fixative in high-value fragrance compositions due to its low volatility and excellent solvating power.
