For businesses operating in the chemical, pharmaceutical, and material science sectors, sourcing reliable intermediates is paramount. (3-Phenylpropyl)dimethylchlorosilane, identified by CAS number 17146-09-7, is one such versatile organosilicon compound that serves as a critical building block. This article aims to guide procurement managers and R&D scientists in understanding the key factors when looking to buy this chemical, especially from China-based manufacturers and suppliers.

Understanding (3-Phenylpropyl)dimethylchlorosilane: Properties and Applications

(3-Phenylpropyl)dimethylchlorosilane is characterized by its clear liquid appearance and its specific molecular formula C11H17ClSi, with a molecular weight of approximately 212.78 g/mol. Its boiling point is noted at 75°C at 0.5 mmHg, and it has a flash point of 103°C. The compound's structure, featuring a phenylpropyl group attached to a dimethylchlorosilane moiety, makes it highly useful in a variety of chemical reactions.

Its primary applications lie in:

  • Organic Synthesis: As a reactive intermediate, it’s invaluable for synthesizing more complex organosilicon compounds, polymers, and specialty chemicals. Researchers often buy this for precise molecular construction.
  • Surface Modification: The silane functionality allows it to chemically bond to surfaces, modifying their properties such as hydrophobicity, adhesion, or reactivity. This is crucial in developing advanced coatings and composites.
  • Material Science: It acts as a building block for advanced materials, including specialized silicones and polymers with tailored properties.
  • Pharmaceutical and Agrochemical Intermediates: Its structure can be incorporated into synthetic routes for active pharmaceutical ingredients (APIs) or agrochemicals.

Key Considerations When Buying

When a procurement manager or a research scientist decides to buy (3-Phenylpropyl)dimethylchlorosilane, several factors must be considered to ensure a successful and cost-effective procurement:

  1. Purity Levels: The original source material often lists purity at 95% or higher. For sensitive applications, particularly in pharmaceuticals or advanced materials, verifying and potentially requesting higher purity grades is crucial. Always check the Certificate of Analysis (CoA) provided by the manufacturer.
  2. Supplier Reliability: Choosing a reputable manufacturer or supplier is key. Look for suppliers with a proven track record, strong quality control systems, and good customer service. Suppliers in China are often competitive in pricing and possess significant manufacturing capacity.
  3. Technical Specifications and Support: Ensure the supplier can provide comprehensive technical data sheets and is responsive to technical inquiries. This is especially important when integrating the chemical into a novel synthesis or formulation.
  4. Pricing and Bulk Orders: For manufacturing quantities, obtaining quotes for bulk purchases is essential. Competitive pricing is often available from Chinese chemical manufacturers, but it's important to balance cost with quality and supply chain stability.
  5. Lead Times and Shipping: Understanding lead times for production and shipping is vital for project planning. Suppliers should be transparent about their delivery schedules, especially for international orders.

Finding the Right Manufacturer and Supplier

When searching for a supplier of (3-Phenylpropyl)dimethylchlorosilane in China, prioritize companies that clearly state their product specifications, CAS number, and offer responsive customer service. Many B2B platforms and chemical directories list various manufacturers. It's advisable to compare multiple suppliers, request samples if possible, and confirm their capabilities for custom synthesis if your project demands slight variations from the standard product.

By carefully evaluating these aspects, businesses can secure a high-quality supply of (3-Phenylpropyl)dimethylchlorosilane, ensuring the efficiency and success of their research, development, and production activities. Connecting with a knowledgeable chemical manufacturer and supplier is the first step towards achieving these goals.
