For procurement specialists and R&D professionals in the chemical and pharmaceutical sectors, a thorough understanding of product specifications is vital before making a purchase. This is especially true for chemical intermediates like 3,4-Dihydro-2-methoxy-2H-pyran (CAS 4454-05-1), a compound essential for the production of glutaraldehyde and other synthetic processes. When you consider to buy this organic intermediate, a detailed look at its specifications ensures it meets the demanding requirements of your applications.

The primary specification for 3,4-Dihydro-2-methoxy-2H-pyran is its purity assay, which is typically stated as ≥98.0%. This high level of purity is critical, as impurities can affect reaction yields and the quality of the final product. The appearance is described as a colorless transparent liquid, a visual indicator of quality that can be confirmed upon receipt. Other important physical parameters that a supplier should readily provide include the density, such as 1.006 g/mL at 25 °C, and the refractive index, typically around 1.441-1.443. These values are important for process control and verification.

As a leading manufacturer and supplier of this intermediate, we ensure that all batches of 3,4-Dihydro-2-methoxy-2H-pyran meet these stringent specifications. We also provide crucial safety information, such as its classification as a flammable liquid with a flash point of 16°C, and its UN number (1993) and packing group (II). This information is vital for safe storage, handling, and transportation, and is typically detailed in the Technical Data Sheet (TDS) and Certificate of Analysis (COA) provided by reliable suppliers.

When you are ready to purchase 3,4-Dihydro-2-methoxy-2H-pyran, consider partnering with a manufacturer that prioritizes quality assurance and customer support. Understanding these specifications will help you compare offerings from different suppliers and make an informed decision. We encourage you to reach out to us, a dedicated manufacturer in China, for detailed product information and to receive a competitive quote for your bulk requirements of CAS 4454-05-1.
