For procurement professionals in the chemical and pharmaceutical industries, securing a consistent supply of high-purity intermediates like Cyclopentene Oxide (CAS 285-67-6) is a core operational challenge. This colorless liquid, known for its utility as an organic synthesis building block, requires careful sourcing to ensure quality and reliability.

When looking to buy Cyclopentene Oxide, key specifications to focus on include its purity level, typically stated as ≥98% by assay. This is crucial for applications ranging from fine chemical synthesis to the development of specialized polymers. Understanding the physical properties—a clear, colorless to very light yellow liquid—also aids in quality assessment.

The CAS number 285-67-6 is the universal identifier, essential for accurate product searches and supplier identification. Many manufacturers and suppliers offer this compound, but for serious B2B procurement, it’s important to work with established entities that can provide comprehensive product data sheets, including storage recommendations and handling guidelines. Proper storage, often at 2-8°C, is vital to maintain its reactivity and purity.

As a vital intermediate, Cyclopentene Oxide finds extensive use in pharmaceutical manufacturing and other complex organic syntheses. Its epoxide functionality makes it highly reactive and useful for creating diverse molecular structures. Procurement managers often seek suppliers who can offer not just competitive pricing but also a stable, long-term supply chain, ensuring uninterrupted production.

When considering manufacturers and suppliers, particularly those operating in China, it’s beneficial to look for companies that emphasize quality control and have a proven track record. Requesting a quote for bulk quantities or specific packaging needs, such as 200kg drums, is a standard procedure to establish commercial terms. Reliable suppliers will also provide timely logistical support and product documentation, facilitating smooth international trade.
