Description

L-Lysine Diisocyanate is a specialized, bifunctional isocyanate derived from the essential amino acid L-lysine, serving as a critical building block for high-performance polymers. Its unique structure enables the synthesis of polyurethanes and polyureas with enhanced biocompatibility, mechanical strength, and controlled degradation profiles. This compound is essential for manufacturers in the biomedical, specialty coatings, and advanced material sectors seeking to develop innovative, bio-based products.

Application

• Biomedical Polyurethanes: A key monomer for synthesizing biodegradable and biocompatible polymers used in tissue engineering scaffolds, drug delivery systems, and surgical implants.
• Specialty Coatings and Adhesives: Used to formulate high-performance, moisture-curing coatings and adhesives with excellent flexibility and chemical resistance for medical devices and electronics.
• Advanced Material Research: Serves as a precursor for novel dendrimers, hyperbranched polymers, and other functional materials with tailored properties.
• Cross-linking Agent: Employed to cross-link polymers containing hydroxyl or amine groups, improving the thermal stability and mechanical properties of the final network.
• Peptide Synthesis and Modification: Utilized as a coupling or modifying agent in peptide chemistry to introduce isocyanate functionality.

Quality Control

Our L-Lysine Diisocyanate is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, isocyanate content determination, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

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); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture ingress.
