Description

n-(Carboxyheptyl)Maleimide is a specialized bifunctional monomer featuring both a reactive maleimide group and a terminal carboxylic acid. This unique structure makes it a valuable building block for synthesizing advanced polymers and functional materials with tailored properties. It is primarily used by researchers and manufacturers in the polymer, specialty chemical, and life sciences industries for applications requiring precise molecular design and cross-linking capabilities.

Application

• Polymer Modification & Cross-linking Agent: Used to introduce reactive sites into polymer backbones (e.g., polyolefins, acrylics) for creating cross-linked networks with enhanced thermal and mechanical stability.
• Synthesis of Specialty Polymers: Serves as a key monomer for producing polyimides, polyamides, and other high-performance polymers with specific solubility or thermal characteristics.
• Bioconjugation & Protein Labeling: The maleimide group selectively reacts with thiol groups (-SH) in cysteine residues, making it useful for attaching peptides, proteins, or drug molecules to carriers or surfaces.
• Surface Functionalization: Employed to modify material surfaces (e.g., nanoparticles, glass, metals) with carboxylic acid groups for further chemical attachment or to alter surface properties.
• Adhesive & Coating Formulations: Incorporated into formulations to improve adhesion, curing speed, and chemical resistance through its dual functionality.
• Intermediate for Pharmaceutical Synthesis: Acts as a versatile chemical intermediate in the development of active pharmaceutical ingredients (APIs) and diagnostic agents.
• Hydrogel Fabrication: Utilized in the creation of hydrogels for biomedical applications, such as drug delivery systems or tissue engineering scaffolds, due to its cross-linking ability.
• Research & Development: A critical reagent in organic and polymer chemistry R&D for exploring new macromolecular architectures and functional materials.

Quality Control

Our n-(Carboxyheptyl)Maleimide is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and NMR/IR for structural confirmation, to ensure it meets high-purity standards suitable for research and industrial synthesis. Certificates of Analysis (COA) detailing specific batch results 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 area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants.
