Description

4-sec-Butylphenyl Isocyanate 97 is a specialized aromatic isocyanate monomer used as a key building block in advanced polymer synthesis. This compound is critical for introducing the bulky sec-butylphenyl moiety into polymer backbones, which can impart unique properties such as enhanced solubility, thermal stability, and specific reactivity profiles. It is primarily sought by R&D chemists and process engineers in the agrochemical, pharmaceutical, and high-performance materials industries for developing novel polyurethanes, coatings, and active pharmaceutical ingredients (APIs).

Application

• Agrochemical Intermediates: Serves as a precursor in the synthesis of modern herbicides and pesticides, where its structural motif can contribute to biological activity and environmental stability.
• Pharmaceutical Synthesis: Used as a reagent for introducing urethane or urea linkages in the development of novel drug candidates and prodrugs.
• Specialty Polyurethanes: A key monomer for producing polyurethane elastomers, coatings, and adhesives with tailored mechanical and chemical resistance properties.
• Advanced Material Research: Employed in R&D for creating novel polymers, liquid crystals, or functional materials that require specific aromatic isocyanate chemistry.
• Cross-linking Agent: Functions as a cross-linker in resin systems to enhance network density and performance characteristics.
• Chemical Modification: Used to modify surfaces or other polymers by grafting isocyanate functional groups for improved adhesion or compatibility.

Quality Control

Every batch of 4-sec-Butylphenyl Isocyanate 97 is produced and tested under a strict quality management system to ensure consistency and reliability for your synthetic processes. Our products undergo rigorous quality testing, including assay and impurity profiling by chromatographic methods, to ensure compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific test results is available upon request and accompanies each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
