In the B2B chemical market, precise specifications and consistent quality are non-negotiable. For intermediates like 2,6-Difluorobenzonitrile (CAS 1897-52-5), understanding these critical parameters is essential for successful application in agrochemical, pharmaceutical, and other industrial syntheses. As a dedicated manufacturer and supplier in China, we place paramount importance on delivering products that meet the highest standards. This article outlines the key specifications that B2B clients should look for when they buy 2,6-difluorobenzonitrile.

The most critical specification for 2,6-Difluorobenzonitrile is its purity, typically stated as Assay or Purity %. For most industrial applications, especially in fine chemicals and pharmaceuticals, a purity of ≥99% is expected. This high level of purity ensures predictable reactivity, minimizes unwanted by-products, and contributes to the overall efficiency and yield of the synthesis process. When sourcing from a Chinese manufacturer, always request a Certificate of Analysis (CoA) to verify these purity levels.

The physical appearance of 2,6-Difluorobenzonitrile is also an important indicator of its quality and handling characteristics. It is commonly described as a colorless solid or an oily liquid, depending on ambient temperature due to its relatively low melting point (25-28 °C). Variations in color, such as a distinct yellow or brown tint, might suggest the presence of impurities or degradation, which is why consistency from a reliable supplier is vital.

Other important specifications to consider when you purchase 2,6-difluorobenzonitrile include its melting point, boiling point (around 197-198 °C), density (approximately 1.246 g/mL at 25 °C), and solubility characteristics. These properties are critical for process design, formulation, and ensuring compatibility with other reagents. For example, understanding its solubility in various organic solvents helps in optimizing reaction conditions and purification methods.

When engaging with a 2,6-difluorobenzonitrile supplier, particularly from China, it's also beneficial to inquire about packaging and storage recommendations. Proper packaging (e.g., 25kg drums) and storage conditions (cool, dry, well-ventilated areas, away from heat sources) are crucial for maintaining the compound's integrity and shelf life. As a leading 2,6-difluorobenzonitrile manufacturer, we ensure our product is packaged and handled with the utmost care to preserve its quality.

In conclusion, specifying and verifying the quality of 2,6-Difluorobenzonitrile is a fundamental step for any B2B client. By focusing on purity (≥99%), consistent appearance, and reliable physical properties, and by partnering with trusted Chinese manufacturers, businesses can ensure the success of their chemical synthesis projects.
