When procuring chemicals for industrial applications, understanding the nuances of sourcing is paramount. Isopropyl Sulfide (CAS 625-80-9) is a compound utilized in various sectors, notably as a flavoring agent and an intermediate in organic synthesis. For purchasing managers and R&D scientists, identifying a dependable manufacturer that offers high-quality Isopropyl Sulfide at competitive prices is crucial. This article provides insights into what buyers should look for when they intend to buy Isopropyl Sulfide.

Understanding Isopropyl Sulfide: Properties and Applications

Isopropyl Sulfide, also known by synonyms such as 2,2'-Thiobispropane, is a colorless liquid characterized by a distinctively unpleasant, sulfurous odor. Its chemical formula is C6H14S, and its CAS number is 625-80-9. The compound finds utility primarily in two key areas: as a flavoring agent in the food industry, contributing specific savory notes, and as a valuable intermediate in organic synthesis, facilitating the creation of more complex molecules for pharmaceuticals, agrochemicals, and material science. Its stability, coupled with its flammable nature, necessitates careful handling and storage, as indicated by its hazard classification as ‘F’ (Highly Flammable) and ‘Xi’ (Irritant).

Key Considerations When Buying Isopropyl Sulfide

For procurement professionals seeking to buy Isopropyl Sulfide, several factors are critical to ensure a successful purchase:

  • Purity Levels: The required purity of Isopropyl Sulfide can vary significantly based on the application. For flavor applications, stringent purity is essential to avoid off-notes. In organic synthesis, specific impurity profiles might be acceptable or even beneficial, but consistency is always key. Always request a Certificate of Analysis (CoA) detailing the purity and any relevant impurities. Suppliers often provide purity in terms of GC (Gas Chromatography) percentage, with common offerings around 98% or 99%.
  • Supplier Reliability: Partnering with a reputable manufacturer or supplier is vital. Look for companies with established quality management systems (like ISO certifications), a transparent supply chain, and positive customer testimonials. A reliable supplier will ensure consistent product availability, timely delivery, and proper documentation, including Safety Data Sheets (SDS). When searching for an Isopropyl Sulfide supplier in China, investigate their manufacturing capabilities and export experience.
  • Pricing and Quotation: The price of Isopropyl Sulfide is influenced by market demand, raw material costs, and order volume. Obtaining multiple quotes is a standard procurement practice. Clearly communicate your required quantity, purity, and delivery timeline to obtain accurate pricing. While unsolicited price ranges might be advertised (e.g., $0-99/kg FOB China), these should be treated as indicative, and a formal quotation is always necessary.
  • Safety and Regulatory Compliance: Ensure that the supplier provides comprehensive SDS and adheres to all relevant safety and transportation regulations. This includes proper labeling, packaging, and documentation for hazardous materials like Isopropyl Sulfide. Understanding the Risk Statements (e.g., R11: Highly Flammable, R36/37/38: Irritating to eyes, respiratory system and skin) and Safety Statements (e.g., S16: Keep away from sources of ignition) is crucial for safe handling and use.

Finding the Right Partner for Isopropyl Sulfide Sourcing

When you need to purchase Isopropyl Sulfide, leveraging industry knowledge can streamline the process. Engaging with chemical manufacturers directly, especially those with a strong presence in markets like China, often provides the best combination of quality and price. Companies specializing in fine chemicals and intermediates are well-positioned to meet the diverse needs of customers. By focusing on these key aspects – purity, supplier reliability, competitive pricing, and safety compliance – businesses can confidently source Isopropyl Sulfide and ensure the success of their respective projects.
