In the specialized field of chemical manufacturing, particularly for dye intermediates, maintaining stringent quality control is non-negotiable. For a compound like 2,6-Diaminoanthraquinone (CAS 131-14-6), its purity directly dictates the performance and quality of the final dyes produced. As a leading supplier, we emphasize the importance of rigorous quality assurance throughout our production process.

The Importance of Purity in 2,6-Diaminoanthraquinone

2,6-Diaminoanthraquinone (C14H10N2O2) serves as a foundational intermediate in the synthesis of high-value vat dyes, such as Reduced Yellow GCN. Impurities, even in small amounts, can lead to several undesirable outcomes in dye production: reduced color yield, altered hue, decreased color fastness, and inconsistent batch-to-batch results. Therefore, achieving and maintaining high purity, often exceeding 99%, is paramount.

Key Quality Control Parameters

Reputable manufacturers employ several methods to ensure the quality of 2,6-Diaminoanthraquinone:

  • Assay and Purity Testing: Techniques like High-Performance Liquid Chromatography (HPLC) are used to determine the precise purity of the compound and identify any trace impurities. Our product consistently demonstrates a high assay, often around 99.8% or higher.
  • Spectroscopic Analysis: Techniques such as NMR and IR spectroscopy confirm the molecular structure, ensuring it is indeed 2,6-Diaminoanthraquinone.
  • Physical Appearance: The characteristic reddish-brown prism appearance is a visual indicator of quality, though it must be correlated with analytical data.
  • Loss on Drying and Ash Content: These tests measure residual moisture and inorganic impurities, respectively, which are kept to a minimum in our product.

For procurement managers and R&D scientists looking to buy 2,6-Diaminoanthraquinone, partnering with a supplier that provides comprehensive Certificates of Analysis (COA) is essential. This documentation verifies that the material meets the required specifications for your applications. We are committed to transparency and provide detailed COAs with every batch, ensuring you can confidently integrate our high-purity 2,6-Diaminoanthraquinone into your synthesis processes.
