Description

Pss-(3-Mercapto)Propyl-Heptaisobutyl Su& CAS NO 480438-85-5 is a specialized organosilicon compound featuring a reactive mercaptopropyl group and a bulky heptaisobutyl silsesquioxane (POSS) cage structure. This unique architecture provides exceptional thermal stability and compatibility while offering a thiol functional handle for chemical modification, making it a valuable advanced material precursor. It is primarily sought after by R&D and production teams in the advanced materials, specialty polymers, and surface coating sectors for developing high-performance nanocomposites, hybrid materials, and functional surfaces.

Application

• Advanced Polymer Nanocomposites: Acts as a functional nanofiller to enhance thermal stability, mechanical strength, and flame retardancy in epoxy, polyurethane, and silicone matrices.
• Hybrid Material Synthesis: Serves as a key building block (monomer or crosslinker) for creating organic-inorganic hybrid materials with tailored properties.
• Surface Modification & Functional Coatings: Used to engineer surface properties, such as adhesion, hydrophobicity, or corrosion resistance, on metals, glass, or polymers.
• Catalyst & Ligand Support: The thiol group can be utilized to anchor metal complexes or nanoparticles for catalytic applications.
• Sensor Technology: Employed in the development of chemical sensors where the POSS cage provides a stable platform and the thiol group enables specific analyte binding.
• Electronics & Optoelectronics: Investigated for use in low-k dielectric materials, encapsulants, and other components requiring high thermal and dimensional stability.

Quality Control

Every batch of Pss-(3-Mercapto)Propyl-Heptaisobutyl Su& CAS NO 480438-85-5 undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocol is designed to meet the stringent requirements of advanced material research and development. Certificates of Analysis (COA) detailing specific batch results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its easily oxidized nature, minimize exposure to air during handling and ensure containers are properly sealed after use.
