Description

Lignin, Organosolv CAS NO 8068-03-9 is a high-purity, sulfur-free biopolymer derived from wood pulp using an organosolv fractionation process. This material matters as a sustainable and versatile platform chemical, offering a renewable alternative to petroleum-based phenols and resins for advanced material synthesis. It is critically needed by industries focused on green chemistry, including manufacturers of bio-based adhesives, carbon fibers, dispersants, and thermoplastic composites seeking to enhance the environmental profile of their products.

Application

• As a renewable phenolic component in the formulation of wood adhesives, such as phenol-formaldehyde (PF) and epoxy resins.
• Production of bio-based carbon fibers and activated carbon precursors for lightweight composites and filtration media.
• Acting as a natural dispersant and stabilizer in concrete admixtures, pesticide formulations, and ceramic processing.
• Manufacture of thermoplastic elastomers and composites to improve biodegradability and mechanical properties.
• Utilization as a UV-absorbing additive in coatings, films, and packaging materials.
• Source for vanillin production and other value-added aromatic chemicals through oxidative depolymerization.
• Component in animal feed binders and soil amendment products for agricultural applications.
• Research and development of advanced biomaterials for 3D printing, hydrogels, and drug delivery systems.

Quality Control

Our Organosolv Lignin is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in chemical composition, purity, and functional performance. Certificates of Analysis (COA) detailing parameters such as ash content, phenolic hydroxyl content, molecular weight distribution, and residual solvent levels are available upon request. We adhere to relevant industry guidelines to support your regulatory and formulation needs.

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). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect flow properties and reactivity.
