For chemical engineers, R&D scientists, and procurement specialists working with fine chemicals, a thorough understanding of a compound's properties and handling requirements is non-negotiable. 2,6-Dimethoxynaphthalene (CAS 5486-55-5) is a critical intermediate, and grasping its chemical characteristics is key to its effective and safe utilization in industrial processes.

Chemical Profile of 2,6-Dimethoxynaphthalene

2,6-Dimethoxynaphthalene is an aromatic organic compound with the molecular formula C12H12O2 and a molecular weight of 188.22 g/mol. Its structure features a naphthalene core substituted with two methoxy groups (-OCH3) at the 2 and 6 positions. This molecular architecture imparts specific reactivity and physical properties that make it valuable in synthesis. It is typically supplied as a white crystal powder, indicative of its purity, with a purity assay usually specified as 99%min.

Key Specifications and Their Importance

When procuring 2,6-Dimethoxynaphthalene, several specifications are vital for ensuring its suitability for intended applications:

  • Appearance: White Crystal Powder. This visually confirms the product's physical state and suggests a lack of significant coloration due to impurities.
  • Purity (Assay): ≥99% min. This is a critical parameter, especially for pharmaceutical intermediates, as higher purity minimizes side reactions and ensures the quality of the final product.
  • Water Content: Typically ≤0.5%. Excess moisture can affect reaction kinetics and product stability.
  • Melting Point: Generally ≥155°C (often cited as 165°C or 152.5-153.5°C). A sharp melting point range within the specified limits indicates high purity and crystalline consistency.

These specifications are crucial for R&D scientists and formulation chemists to predict and control reaction outcomes. Procurement managers must ensure their chosen suppliers consistently meet these standards, often verified through a Certificate of Analysis (CoA).

Storage and Safe Handling Practices

Proper storage is essential to maintain the quality and integrity of 2,6-Dimethoxynaphthalene. It should be stored in a sealed, dark, dry, and cool place to prevent degradation from light, moisture, and air. When handling the chemical, standard laboratory safety precautions should be observed. This includes wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and lab coats. Good ventilation in the workspace is also recommended to minimize exposure to dust.

Procurement and Supply Chain Considerations

For businesses looking to buy 2,6-Dimethoxynaphthalene, sourcing from reliable manufacturers, especially those in China, is often the most cost-effective strategy. Companies should inquire about packaging options (commonly 25kg drums) and delivery schedules, which are often around 5-7 days after payment receipt. Building a relationship with a trusted supplier ensures not only competitive pricing but also consistent product quality, crucial for large-scale production and for R&D projects requiring dependable chemical inputs.
