In the global chemical supply chain, China has emerged as a leading producer of essential intermediates like 2-Ethyl Anthraquinone (2-EAQ). For businesses worldwide that rely on this compound for hydrogen peroxide production or dye synthesis, understanding how to procure it effectively from Chinese manufacturers is crucial. This guide outlines key considerations for buyers seeking to purchase 2-ethyl anthraquinone with confidence.

The Global Demand for 2-EAQ

2-Ethyl Anthraquinone (CAS 84-51-5) is a high-demand intermediate. Its primary application as a catalyst in the anthraquinone process for producing hydrogen peroxide means that as global demand for H2O2 grows, so does the need for reliable 2-EAQ supply. Additionally, its use in creating various dyes—reducing, dispersed, and reactive types—further cements its importance across multiple industries. The rapid development in these sectors has led to significant growth in the production and supply of 2-EAQ, particularly from China.

Key Specifications to Verify When Buying 2-EAQ

When evaluating potential suppliers, especially when looking to buy 2-ethyl anthraquinone 99% from China, buyers must meticulously check product specifications. These typically include:

  • Purity: A minimum of 99% assay is standard for industrial applications.
  • Appearance: Light yellow flake or powder.
  • Melting Point: Consistently within the range of 107-111°C.
  • Impurities: Low levels of benzene insoluble matter (≤0.05%), moisture (≤0.20%), and trace metals (iron, chlorine, sulfur) are vital for process efficiency and final product quality.

A reputable hydrogen peroxide intermediate manufacturer or dye intermediate supplier will readily provide a detailed Certificate of Analysis (COA) for their products.

Finding the Right Manufacturer: China Sourcing Strategies

Several strategies can help businesses identify reliable 2-EAQ manufacturers in China:

  1. Direct Manufacturer Inquiry: Focus on companies with dedicated manufacturing facilities rather than trading companies. Look for manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. that specialize in fine chemicals and intermediates.
  2. Technical Data and Support: Ensure the supplier provides comprehensive technical documentation (TDS, MSDS) and responsive customer service for technical inquiries.
  3. Price Benchmarking: Request quotes and compare the CAS 84-51-5 price from multiple qualified manufacturers to ensure competitive pricing. Be wary of prices that seem too low, as they may indicate lower quality.
  4. Logistics and Packaging: Confirm that the supplier offers appropriate packaging (e.g., 25kg or 500kg bags) and can arrange for reliable international shipping.
  5. Quality Certifications: While not always mandatory, look for suppliers with ISO certifications or other quality management system approvals.

The efficiency of hydrogen peroxide production and the quality of synthesized dyes are directly influenced by the intermediate used. By implementing a thorough sourcing strategy and prioritizing quality and reliability, businesses can confidently secure their supply of 2-Ethyl Anthraquinone from China's robust chemical manufacturing sector. Engaging directly with established manufacturers ensures not only competitive pricing but also the consistent quality essential for industrial success.
