Description

1,5-Hexanediol is a high-purity, linear aliphatic diol with versatile chemical functionality, serving as a critical building block in advanced polymer synthesis. Its bifunctional nature, featuring two primary hydroxyl groups, makes it an essential monomer for producing high-performance polyurethanes, polyesters, and specialty resins. This compound is particularly valued in the coatings, adhesives, and pharmaceutical intermediate sectors for its ability to impart flexibility, hydrophilicity, and controlled reactivity to final products.

Application

• Polymer Synthesis: A key monomer for producing flexible polyurethane elastomers, coatings, and adhesives.
• Resin Modifier: Used in unsaturated polyester resins and alkyd resins to modify flexibility and durability.
• Pharmaceutical Intermediates: Serves as a precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems.
• UV-Curable Systems: Acts as a reactive diluent and crosslinker in UV-curable inks, coatings, and 3D printing resins.
• Plasticizers: Employed as a non-phthalate plasticizer and compatibilizer in various polymer formulations.
• Personal Care: Used in the formulation of hair sprays, skin creams, and other cosmetic products as a humectant and solvent.
• Chemical Intermediate: A versatile building block for synthesizing plasticizers, surfactants, and corrosion inhibitors.

Quality Control

Our 1,5-Hexanediol is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against comprehensive specifications, including identity, assay, and impurity profiles. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support audits and can provide material for customer qualification to meet GMP, ISO, and REACH requirements as applicable.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
