Description

4,7-Decanediol is a valuable aliphatic diol characterized by its two hydroxyl groups positioned at the 4 and 7 carbon atoms of a ten-carbon chain. This specific molecular structure makes it a versatile intermediate and building block for synthesizing specialized polymers, plasticizers, and fine chemicals. It is particularly relevant for industries requiring high-performance materials with tailored properties, such as advanced polymer manufacturing and specialty chemical synthesis.

Application

• Polymer Synthesis: Serves as a key monomer or chain extender in the production of polyurethanes, polyesters, and other specialty polymers, influencing flexibility and thermal properties.
• Plasticizer Production: Used as a raw material for manufacturing ester-based plasticizers, which are added to polymers to improve their workability, durability, and flexibility.
• Lubricant & Functional Fluid Formulation: Acts as a base or intermediate for creating synthetic lubricants and high-performance functional fluids with specific viscosity and stability profiles.
• Surface Active Agents: Employed in the synthesis of non-ionic surfactants and emulsifiers for use in industrial cleaning, agrochemicals, and coatings.
• Pharmaceutical & Cosmetic Intermediates: Functions as a chemical building block in the synthesis of active pharmaceutical ingredients (APIs) and cosmetic ingredients where specific diol chemistry is required.
• Crosslinking Agent: Utilized in coatings, adhesives, and resin systems to promote crosslinking, enhancing chemical resistance and mechanical strength of the final product.

Quality Control

Our 4,7-Decanediol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and chemical composition. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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. Keep away from strong oxidizing agents.
