For research and development scientists and procurement specialists in the chemical and textile industries, the quality of raw materials is paramount. 1,5-Diaminoanthraquinone (CAS 129-44-2) is a critical intermediate, and ensuring its purity and consistency is essential for successful dye synthesis and product development. This article focuses on quality assurance when you plan to buy 1,5-Diaminoanthraquinone, particularly from Chinese suppliers, offering insights and best practices.

Understanding the Importance of Quality in 1,5-Diaminoanthraquinone

1,5-Diaminoanthraquinone, a dark red to brown-red powder, serves as a vital precursor in the creation of various dyes. Its chemical structure (C14H10N2O2, MW: 238.24) dictates its reactivity and the properties of the final dyes. The primary quality metric for this intermediate is its purity, typically specified at a minimum of 97%. High purity ensures predictable reaction outcomes, vibrant and stable colors, and compliance with industry standards. Lower purity can lead to issues such as inconsistent shades, reduced dye strength, poor lightfastness, and potential contamination of the final product, making it imperative to source from manufacturers committed to quality.

Key Quality Indicators to Verify

When you intend to buy 1,5-Diaminoanthraquinone, always look for the following quality indicators:

  • Certificate of Analysis (CoA): A comprehensive CoA from the supplier is the most important document. It should detail the purity (e.g., 97% min), impurity profiles, physical appearance, and test methods used.
  • Physical Appearance: Confirm that the product matches the expected color and form (dark red to brown-red powder).
  • CAS Number Verification: Ensure the product is indeed 1,5-Diaminoanthraquinone (CAS 129-44-2).
  • Manufacturing Standards: Inquire about the manufacturer’s quality management systems, such as ISO certifications, which indicate a commitment to consistent processes.
  • Batch-to-Batch Consistency: For ongoing supply needs, consistent quality across different batches is crucial. Reputable manufacturers maintain strict process controls to ensure this.

The Role of Chinese Manufacturers in Quality Supply
