For businesses in the chemical and textile industries, securing a reliable supply of high-purity raw materials is paramount. 1,4-Diaminoanthraquinone (CAS 128-95-0) stands out as a critical dye intermediate, essential for producing a spectrum of vibrant colors used in various applications. This article aims to guide procurement managers and R&D scientists on how to best source this vital compound, focusing on quality, consistency, and cost-effectiveness from reputable manufacturers.

Understanding 1,4-Diaminoanthraquinone (CAS 128-95-0)

1,4-Diaminoanthraquinone is an organic compound characterized by its dark purple crystalline appearance. Its molecular formula is C14H10N2O2, with a molecular weight of 238.24 g/mol. The compound's primary utility lies in its role as an intermediate in the synthesis of anthraquinone dyes. These dyes are highly valued for their excellent color fastness and brilliance, making them indispensable for dyeing synthetic fibers like polyester, as well as for applications in printing inks and plastics. The typical assay required by end-users is a minimum of 99% purity to ensure optimal performance and predictable results in their formulations.

Key Applications and Why Purity Matters

The versatility of 1,4-Diaminoanthraquinone is evident in its broad application range. It is a precursor for numerous dye classes, including Disperse Violet 1, Disperse Blue 60, and various vat dyes. In the textile industry, the demand for vibrant, long-lasting colors means that the quality of intermediates directly impacts the final product. Using a lower-purity 1,4-Diaminoanthraquinone can lead to inconsistent shades, reduced color yield, and potential contamination issues. Therefore, R&D scientists and product formulators prioritize sourcing from manufacturers who can guarantee a consistent, high-purity product. The demand for this chemical is driven by the growing textile industry and the continuous innovation in color chemistry.

Procurement Strategies: Finding the Right Supplier

When looking to buy 1,4-Diaminoanthraquinone, it’s crucial to partner with established manufacturers and suppliers. China has emerged as a significant global hub for chemical production, offering competitive pricing and substantial production capacities. Procurement managers should look for suppliers who:

  • Provide Certificates of Analysis (COA): A detailed COA confirming the 99% minimum assay and other critical parameters is non-negotiable.
  • Demonstrate Strong Quality Control: Look for evidence of robust quality assurance systems, including in-house testing and adherence to international standards.
  • Offer Competitive Pricing: Compare quotes from multiple verified suppliers to ensure you are getting the best market price for bulk purchases. Understanding the market price for this chemical is key to making informed decisions.
  • Ensure Supply Chain Stability: A reliable supplier will have ample stock and efficient logistics to meet your production schedules. Enquiring about their monthly capacity and delivery times is essential.
  • Provide Technical Support: A good chemical supplier can offer technical insights and assistance, especially for new product development or troubleshooting.

Making an Informed Purchase Decision

For businesses seeking to purchase 1,4-Diaminoanthraquinone, engaging directly with manufacturers or their authorized distributors is the most effective approach. Initiating an inquiry with potential suppliers is the first step. Be prepared to specify your required quantity, desired purity, and any specific quality certifications needed. Many leading suppliers offer sample testing, which is highly recommended to verify product quality before committing to larger orders. By focusing on these aspects, companies can secure a dependable source of this critical dye intermediate, ensuring the quality and competitiveness of their own products in the global market.
