For businesses that rely on Adipic Acid (Hexanedioic Acid, CAS 124-04-9) for their manufacturing processes, particularly in polymer synthesis and specialty chemical production, quality assurance is not just a preference—it's a necessity. The purity, consistency, and physical characteristics of Adipic Acid directly impact the efficiency of reactions, the quality of finished products, and ultimately, the profitability of operations. As a reputable manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. places immense emphasis on rigorous quality control to meet the exacting demands of global industrial clients.

Critical Quality Parameters for Industrial Adipic Acid:

When procuring industrial-grade Adipic Acid, buyers should focus on several key quality indicators:

  • Assay (Purity): The primary specification is the assay, typically measured by acidimetric titration. Industrial grades usually require a purity of 99.0% or higher. Impurities can affect polymerization reactions, leading to undesired side products or compromised material properties.
  • Melting Range: A sharp melting point within the specified range (e.g., 151-154 °C) indicates high purity and consistent crystalline structure. A broad or depressed melting range can signal the presence of impurities.
  • Appearance: The product should consistently appear as a white crystalline powder. Discoloration might suggest degradation or contamination.
  • Moisture Content: Low moisture content is crucial, as water can interfere with certain chemical reactions, especially polymerization. Typical specifications limit moisture to very low percentages.
  • Ash Content: Ash content, representing inorganic residue after ignition, should be minimal, indicating the absence of inorganic contaminants.
  • Acidity/pH: While Adipic Acid is an acid, its pH in solution is a measurable property that should fall within expected ranges, reflecting its strength and purity.
  • Particle Size Distribution: For certain applications, particularly in solid-state reactions or formulations, the particle size distribution of the Adipic Acid powder can be important for dissolution rates and handling.
