For businesses operating in the chemical and materials science sectors, efficient and informed procurement of specialty chemicals is paramount. Diethylphosphatoethyltriethoxysilane (CAS 757-44-8) is one such compound, valued for its unique phosphonate and silane functionalities. This guide is tailored for B2B procurement managers, R&D scientists, and formulation chemists, providing insights into the properties, applications, and the best practices for purchasing this versatile chemical intermediate from China.

Understanding Diethylphosphatoethyltriethoxysilane (CAS 757-44-8)
Diethylphosphatoethyltriethoxysilane is classified as an organophosphorus silane. Its chemical structure, C12H29O6PSi, features a phosphonate ester group linked via an ethyl chain to a triethoxysilane group. This structure dictates its utility:

  • Silane Reactivity: The triethoxysilane moiety readily undergoes hydrolysis and condensation, allowing it to form siloxane networks or bond covalently to inorganic surfaces.
  • Phosphonate Functionality: The phosphonate ester group offers capabilities such as metal surface adhesion, potential corrosion inhibition, and flame retardancy.
  • Intermediate Chemical: It is commonly used as an intermediate in the synthesis of more complex silicone compounds and specialty polymers.

Key Applications for B2B Buyers
As a specialty chemical, Diethylphosphatoethyltriethoxysilane finds application in several key industries:

  • Silicone Manufacturing: It is a crucial building block for synthesizing specialized silicone fluids, resins, and elastomers with tailored properties.
  • Coatings and Adhesives: Its ability to promote adhesion and provide corrosion resistance makes it valuable for high-performance coatings and adhesives, especially on metallic substrates.
  • Polymer Modification: It can be used to enhance the mechanical strength, thermal stability, or flame retardancy of various polymer systems.
  • Surface Treatments: Useful for modifying the surfaces of inorganic materials to improve compatibility with organic matrices.

How to Purchase Diethylphosphatoethyltriethoxysilane from China: A Procurement Strategy
When sourcing chemical intermediates like CAS 757-44-8, establishing a robust procurement strategy is essential. Here are key steps:

  • Identify Reputable Manufacturers: Look for suppliers with a strong online presence, clear product specifications, and established export capabilities. Manufacturers in China are often a primary source for specialty silanes due to advanced production capabilities and competitive pricing.
  • Verify Product Specifications: Always request and review the Technical Data Sheet (TDS) and Safety Data Sheet (SDS). For Diethylphosphatoethyltriethoxysilane, confirm purity (e.g., 92% or higher), physical appearance (typically a clear liquid), and other critical parameters.
  • Inquire About Pricing and Minimum Order Quantities (MOQ): Contact suppliers directly to get the latest pricing for your required quantities. Understanding MOQs is crucial for managing inventory and production planning.
  • Discuss Packaging and Logistics: Confirm that the supplier can meet your packaging requirements (e.g., specific container types, volumes) and has experience with international shipping to your location.
  • Request Samples: Before placing a large order, it is advisable to obtain samples for internal testing and quality validation.
