For professionals in the chemical industry, having a clear understanding of key intermediates is essential for successful product development and manufacturing. 5-tert-Butyl-m-xylene, identified by its CAS number 98-19-1, is a compound of interest due to its utility as an organic intermediate. This article provides a comprehensive overview of its properties, the importance of purity, and effective strategies for procurement, particularly from Chinese manufacturers and suppliers.

What is 5-tert-Butyl-m-xylene?

5-tert-Butyl-m-xylene is an aromatic hydrocarbon with the chemical formula C12H18. Its structure consists of a benzene ring substituted with two methyl groups at the 1 and 3 positions (meta-xylene) and a tert-butyl group at the 5 position. This specific arrangement gives it unique characteristics that are leveraged in various chemical synthesis processes. Its molecular weight is approximately 162.276 g/mol.

Key Physical and Chemical Properties

Understanding the properties of 5-tert-Butyl-m-xylene is crucial for its application. While specific details can vary slightly by supplier, general properties include:

  • Appearance: Typically a clear liquid.
  • Melting Point: Around -22°C.
  • Boiling Point: In the range of 207-209°C.
  • Flash Point: Approximately 84°C (183°F), classifying it as a combustible liquid.
  • Purity: Commonly available at purities of 98% or higher.
  • Solubility: Generally soluble in organic solvents and sparingly soluble in water.

The tert-butyl group influences its reactivity, often providing steric hindrance and electron-donating effects that are important considerations for R&D scientists designing synthesis routes.

The Importance of Purity in Procurement

For any chemical intermediate, purity is a critical factor, and 5-tert-Butyl-m-xylene (CAS 98-19-1) is no exception. High purity ensures:

  • Reliable Reaction Outcomes: Minimizing side reactions and ensuring predictable yields in synthesis.
  • Consistent Product Quality: Crucial for the performance and safety of downstream products.
  • Compliance: Meeting industry standards and regulatory requirements.

Procurement managers and R&D scientists should always inquire about the purity specifications and any potential trace impurities from their suppliers. Purchasing from manufacturers that provide Certificates of Analysis (CoA) is a best practice.

Sourcing 5-tert-Butyl-m-xylene from China

China is a significant global producer of chemical intermediates, making it a primary source for compounds like 5-tert-Butyl-m-xylene. To effectively buy this product from Chinese manufacturers and suppliers:

  • Identify Reputable Suppliers: Look for companies with a proven track record in exporting chemicals. Check for certifications and customer testimonials.
  • Compare Pricing and Terms: Obtain quotes from multiple suppliers to ensure competitive pricing for 5-tert-Butyl-m-xylene (CAS 98-19-1). Pay attention to payment terms and Incoterms.
  • Verify Supply Capability: Confirm that the supplier can meet your required quantities and delivery timelines.
  • Ensure Documentation: Make sure the supplier can provide all necessary documentation, including SDS and CoAs.

Conclusion

5-tert-Butyl-m-xylene (CAS 98-19-1) is a valuable intermediate with well-defined properties. Understanding these properties and prioritizing purity are key when you decide to buy. By partnering with reliable Chinese manufacturers and suppliers, procurement professionals and R&D scientists can ensure a consistent and high-quality supply of this important chemical, facilitating their research and production goals.
