One such critical intermediate is 3-(N-Phenylamino)propyltrimethoxysilane, identified by its CAS number 3068-76-6. This organosilane is highly valued for its unique properties, particularly its efficacy as an adhesion promoter and its contribution to thermal stability in various resin systems. For R&D scientists and procurement professionals looking to buy high-performance chemicals, understanding the utility of CAS 3068-76-6 is essential.

The Chemical Identity and Properties of CAS 3068-76-6

3-(N-Phenylamino)propyltrimethoxysilane, also known by IUPAC names such as N-(3-trimethoxysilylpropyl)aniline, is characterized by its chemical structure that combines an amino group, a propyl chain, and trimethoxysilane functionality, along with a phenyl ring. This specific arrangement provides it with a unique set of properties:

  • Adhesion Promotion: The silane moiety readily bonds to inorganic surfaces, while the phenylamino group interacts favorably with organic polymers, creating a strong interface. This makes it an excellent choice for enhancing the bond strength in composite materials, coatings, and adhesives.
  • Thermal Stability: The presence of the phenyl group significantly enhances the molecule's thermal resistance compared to simpler amino silanes. This property is crucial for applications operating at elevated temperatures.
  • Reactivity: It is reactive with a wide range of resins, including epoxies, polyurethanes, phenolics, and acrylics, making it a versatile component in formulation.
  • Appearance: Typically presented as a colorless to yellowish clear liquid.

When you search for chemical suppliers, looking for detailed technical data sheets for compounds like CAS 3068-76-6 will provide critical insights into purity, handling, and application suitability. Buying from a reputable manufacturer ensures you receive a product that meets stringent quality standards.

Key Industrial Applications

The demand for CAS 3068-76-6 stems from its significant contribution to material performance enhancement:
