Description

1,8-Octanediol is a high-purity, linear aliphatic diol with the CAS number 629-41-4, serving as a versatile and valuable building block in advanced organic synthesis. Its bifunctional structure, featuring two terminal hydroxyl groups separated by a flexible eight-carbon chain, makes it an essential monomer for creating polymers with specific mechanical and thermal properties. This compound is particularly sought after by manufacturers in the polymer, pharmaceutical intermediate, and specialty chemical industries for producing polyesters, plasticizers, and performance additives.

Application

• Polymer Synthesis: A key monomer for the production of specialty polyesters, polyurethanes, and co-polymers, imparting flexibility and specific chain length.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where its diol functionality allows for conjugation and controlled release.
• Plasticizers and Additives: Acts as a precursor or component in plasticizers to improve the flexibility and durability of plastics like PVC.
• Cosmetic and Personal Care Ingredients: Employed in the formulation of emollients, humectants, and as a solvent or carrier in fragrances and skin care products.
• Lubricants and Functional Fluids: Serves as a base or intermediate for synthetic lubricants and functional fluids requiring high thermal stability and low volatility.
• Cross-linking Agent: Utilized in coatings, adhesives, and resin systems as a cross-linker to enhance network density and material performance.
• Chemical Research & Development: A valuable reagent in organic chemistry R&D for constructing complex molecular architectures.

Quality Control

Our 1,8-Octanediol is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against comprehensive specifications, including identity, assay, and impurity profiles. Certificates of Analysis (COA) documenting results from GC, HPLC, and other relevant analytical methods are provided with every shipment 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.
