For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing reliable intermediates is paramount. 1,3-Bis(4-hydroxybutyl)tetramethyldisiloxane (CAS 5931-17-9) is a highly versatile organosilicon compound that serves as a critical building block in numerous synthesis pathways and material science applications. Understanding how to effectively source this chemical can significantly impact project timelines and product quality. As a leading chemical manufacturer and supplier based in China, we aim to illuminate the key factors to consider when you need to buy this essential intermediate.

Understanding the Chemical: Properties and Applications
1,3-Bis(4-hydroxybutyl)tetramethyldisiloxane is characterized by its siloxane backbone, which imparts excellent thermal stability and chemical resistance. The presence of two terminal hydroxyl groups makes it highly reactive and suitable for a wide array of applications, including as an end-capper for carbinol-terminated silicones, a key component in coatings, adhesives, sealants, and elastomers (CASE), and in advanced material synthesis. Its utility in modifying polymer properties and creating novel functional materials makes it indispensable for research and development across various sectors.

Key Considerations for Sourcing
When seeking to purchase 1,3-Bis(4-hydroxybutyl)tetramethyldisiloxane, several critical aspects should be evaluated:

  • Purity and Specifications: The required purity level often dictates the suitability for specific applications. Ensure the supplier can provide detailed Certificates of Analysis (CoA) confirming purity, CAS number (5931-17-9), and adherence to your technical specifications. For chemical synthesis, high purity is often non-negotiable.
  • Supplier Reliability and Reputation: Opt for manufacturers or established suppliers with a proven track record. Companies with ISO certifications and a history of consistent product quality and delivery are preferable. A responsive supplier will be able to provide technical support and readily answer queries regarding the product's properties and applications.
  • Pricing and Lead Times: Competitive pricing is a significant factor, especially for bulk orders. However, it should not come at the expense of quality or reliability. Understanding the lead times for production and delivery from your chosen manufacturer is crucial for effective project planning. Requesting quotes from multiple suppliers, especially from major manufacturing hubs like China, can help secure the best value.
  • Customization and Technical Support: For specialized R&D projects, the ability of a supplier to offer custom synthesis or tailored packaging can be highly advantageous. Furthermore, accessible technical support can assist in optimizing the use of the chemical in your specific formulations or synthesis routes.
