Description

Disiloxanamine, 1,1,3,3,3-Pentamethyl-n-(Trimethylsilyl)- is a specialized organosilicon compound that serves as a versatile silylating agent and reactive intermediate in advanced synthesis. Its core value lies in its ability to introduce protective trimethylsilyl groups and modify surface chemistries, enabling precise control in material and pharmaceutical manufacturing. This high-purity chemical is essential for R&D and production in industries such as silicone polymers, pharmaceuticals, and surface coatings, where reliable performance and consistent quality are paramount.

Application

• Silylating Agent: Used to protect reactive functional groups (e.g., -OH, -NH) in complex organic and pharmaceutical synthesis.
• Silicone Polymer Modification: Acts as a cross-linking agent or chain terminator in the production of specialty silicones and siloxane elastomers.
• Surface Treatment: Imparts hydrophobic properties to glass, silica, and other inorganic materials for coatings and composites.
• Chemical Intermediate: Serves as a key building block for synthesizing more complex organosilicon compounds and catalysts.
• Adhesive & Sealant Formulation: Enhances adhesion and stability in high-performance silicone-based adhesives and sealants.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) requiring silyl protection strategies.

Quality Control

Our Disiloxanamine, 1,1,3,3,3-Pentamethyl-n-(Trimethylsilyl)- is manufactured under strict quality systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) documenting full specifications are 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, well-ventilated area at room temperature (15-25°C). Due to its highly volatile and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and maintain product integrity. Keep away from heat, sparks, and open flame.
