Description

1,20-Eicosanediol CAS NO 7735-43-5 is a long-chain aliphatic diol, a versatile bifunctional building block prized for its ability to impart flexibility, hydrophobicity, and specific chain length into polymer backbones. This compound matters for formulators and researchers seeking to create specialized polyesters, polyurethanes, and other performance materials with tailored physical properties. It is needed by industries focused on advanced material science, including specialty polymer synthesis, lubricant additives, and cosmetic ingredient development.

Application

• Polymer Synthesis: A key monomer for producing long-chain polyesters and polyurethanes, contributing to flexibility, toughness, and water resistance in coatings, adhesives, and elastomers.
• Lubricant & Grease Formulation: Used as an intermediate or additive to enhance viscosity index, thermal stability, and lubricity in synthetic lubricants and high-performance greases.
• Cosmetic & Personal Care: Serves as an emollient and viscosity modifier in premium skin care formulations, creams, and lotions, providing a smooth, non-greasy feel.
• Surface Coatings: Incorporated into resin systems for coatings that require excellent adhesion, chemical resistance, and durability.
• Pharmaceutical Intermediates: Utilized in the synthesis of prodrugs, drug delivery systems, and other bioactive molecules requiring specific lipophilic spacers.
• Chemical Research & Development: Acts as a standard or building block in organic synthesis for creating novel surfactants, plasticizers, and dendritic polymers.

Quality Control

Our 1,20-Eicosanediol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting specifications for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling properties.
