Description

N,n-Dodecamethylenebisacrylamide is a high-purity, difunctional crosslinking agent featuring two reactive acrylamide groups separated by a long dodecamethylene spacer. This compound matters for its ability to create stable, flexible polymer networks, significantly enhancing the mechanical properties and durability of the final materials. It is primarily needed by manufacturers in the polymer, specialty coatings, and advanced materials industries seeking to develop high-performance, cross-linked products.

Application

• Polymer Crosslinking Agent: A key monomer for synthesizing cross-linked polyacrylamides and hydrogels with tailored porosity and swelling properties.
• Hydrogel Production: Used in the manufacture of superabsorbent polymers (SAPs) for hygiene products, agricultural water retention, and medical wound dressings.
• Chromatography Media: Serves as a crosslinker in the production of rigid, high-performance gel filtration and affinity chromatography columns for biopharmaceutical separation.
• Electrophoresis Gels: Employed in the formulation of polyacrylamide gel electrophoresis (PAGE) gels for precise protein and nucleic acid analysis in life science research.
• Contact Lens Material: A component in the synthesis of certain silicone hydrogel polymers, contributing to oxygen permeability and dimensional stability.
• Adhesive & Sealant Formulations: Imparts enhanced cohesive strength, chemical resistance, and thermal stability to advanced industrial adhesives and sealants.
• Drug Delivery Systems: Utilized in creating controlled-release matrices and micro/nanoparticles for targeted pharmaceutical applications.
• Ion-Exchange Resins: Acts as a crosslinker in the synthesis of resins used for water purification and metal recovery processes.

Quality Control

Our N,n-Dodecamethylenebisacrylamide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for crosslinking efficiency. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
