Description

3,3'-[(1,1,3,3-Tetramethyl-1,3-Propanedisiloxanediyl)Bis(4,1-Butanediyloxy)]Bis(Benzenamine) is a specialized organosilicon compound featuring a central disiloxane bridge linked to aromatic amine groups via flexible butyloxy spacers. This unique molecular architecture makes it a valuable high-performance intermediate for advanced material synthesis, particularly where thermal stability and controlled reactivity are required. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular frameworks.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and drug candidates, leveraging its amine functionality and silicon-based backbone.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and pesticides where its structural properties can enhance efficacy and environmental profile.
• Specialty Polymer & Resin Modifier: Serves as a cross-linking agent or monomer for producing high-performance silicones, epoxy resins, and polyimides with improved thermal and mechanical properties.
• Surface Modification & Adhesion Promoter: Functionalizes inorganic surfaces (e.g., glass, silica) to improve compatibility and adhesion in composite materials and coatings.
• Liquid Crystal & OLED Material Precursor: Employed in the synthesis of organic semiconductors and liquid crystal compounds for electronic display technologies.
• Chelating Ligand for Catalysts: Acts as a precursor for creating sophisticated ligands used in homogeneous catalysis for fine chemical production.

Quality Control

Every batch of our 3,3'-[(1,1,3,3-Tetramethyl-1,3-Propanedisiloxanediyl)Bis(4,1-Butanediyloxy)]Bis(Benzenamine) undergoes rigorous analytical testing to ensure high purity and batch-to-batch consistency, critical for sensitive synthetic applications. Our quality assurance protocols are designed to meet the stringent requirements of GMP and ISO 9001 standards where applicable. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
