Description

1 3-Phenylene Diisothiocyanate 97 is a high-purity aromatic diisothiocyanate compound, serving as a critical bifunctional building block for the synthesis of advanced materials and specialty chemicals. Its primary value lies in its ability to introduce thiourea linkages and isothiocyanate functional groups into polymer backbones and small molecules, enabling precise control over material properties. This product is essential for R&D and production teams in the polymer, pharmaceutical, and agrochemical industries seeking to develop novel polymers, cross-linking agents, or bioactive compounds.

Application

• Polymer Synthesis: Key monomer for producing polyurethanes, polyureas, and specialty thiourethane polymers with enhanced thermal and chemical resistance.
• Cross-linking Agent: Used to cross-link polymers containing amine groups, improving the mechanical strength and durability of coatings, adhesives, and elastomers.
• Pharmaceutical Intermediates: Serves as a precursor in the synthesis of potential drug candidates and diagnostic agents, particularly those targeting specific biological pathways.
• Agrochemicals: Employed in the research and development of novel pesticides and herbicides, where the isothiocyanate group can act as a reactive handle.
• Material Science Research: Used in the development of advanced functional materials, including liquid crystals, dendrimers, and metal-organic frameworks (MOFs).
• Surface Modification: Facilitates the covalent attachment of molecules to surfaces (e.g., glass, metals) for creating biosensors or functionalized nanomaterials.

Quality Control

Our 1 3-Phenylene Diisothiocyanate 97 is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure it meets the declared purity and impurity profile specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong bases, amines, and alcohols.
