Description

Adipic Dihydrazide CAS NO 1071-93-8 is a high-purity, white crystalline dihydrazide derivative of adipic acid, serving as a critical crosslinking agent and reactive intermediate in polymer chemistry. Its bifunctional hydrazide groups provide excellent reactivity for forming thermally stable bonds, making it essential for enhancing material durability and performance. This compound is primarily sought by manufacturers in the polymer, coatings, and specialty chemical industries for applications requiring robust crosslinking and chain extension.

Application

• Crosslinking Agent for Epoxy Resins: Imparts improved thermal and chemical resistance to cured epoxy systems used in advanced composites and adhesives.
• Chain Extender for Polyurethanes: Reacts with isocyanates to modify polymer backbone properties, enhancing tensile strength and thermal stability in elastomers and foams.
• Curing Agent for Powder Coatings: Used as a hardener in thermosetting powder coatings to achieve durable, scratch-resistant, and high-gloss finishes.
• Intermediate for Pharmaceutical Synthesis: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Stabilizer and Modifier for Polymers: Acts as a property modifier in nylon and other polyamides to improve melt stability and processing characteristics.
• Textile Finishing Agent: Utilized in crosslinking formulations for textile resins to create wrinkle-resistant and durable-press fabrics.
• Water Treatment Chemical: Functions as a scale and corrosion inhibitor in industrial water treatment formulations.
• Adhesive Formulation: Enhances the performance and heat resistance of structural and industrial adhesives.

Quality Control

Our Adipic Dihydrazide is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to meet exacting industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is 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 a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
