For chemical procurement specialists and production managers, understanding the manufacturing processes and quality control measures behind key intermediates is crucial for ensuring supply chain reliability and product consistency. 1,4-Dihydroxyanthraquinone, also known as Quinizarin or Solvent Orange 86 (CAS 81-64-1), is a vital compound with widespread applications, particularly in the dye industry. As a dedicated manufacturer, we believe in transparently sharing insights into how we produce this essential chemical, ensuring our clients receive only the highest quality materials.

The synthesis of 1,4-Dihydroxyanthraquinone typically involves reacting phthalic anhydride with either 4-chlorophenol followed by hydrolysis, or with hydroquinone under specific conditions. These reactions require precise control over temperature, reaction time, and reagent ratios to achieve optimal yields and purity. Our manufacturing facilities are equipped with advanced reactors and purification systems designed to manage these parameters effectively. The focus is not just on producing the compound, but on consistently achieving the desired purity levels, whether it be the 96% crude grade for broader applications or the 99% fine grade for more sensitive processes.

Quality control is integrated at every stage of our manufacturing process. From the sourcing of raw materials to the final packaging of the product, rigorous testing is performed. For 1,4-Dihydroxyanthraquinone, this includes analytical techniques such as High-Performance Liquid Chromatography (HPLC) to determine purity, moisture content analysis, and checks for toluene-insoluble matter. These tests ensure that the final product meets or exceeds industry standards and customer specifications. For buyers looking to purchase 1,4-dihydroxyanthraquinone, partnering with a manufacturer that provides detailed Certificates of Analysis (COA) for each batch is essential for confidence.

Our commitment as a manufacturer extends to ensuring a stable supply. With a significant plant capacity and a robust global export network, we are well-positioned to meet the demands of diverse industries worldwide. Whether you require Quinizarin for textile dye production, industrial coloring, or organic synthesis, our production capabilities are designed to ensure timely delivery. Understanding the competitive quinizarin price from a direct manufacturer like us can also offer significant economic advantages for your business.

We also pay close attention to packaging and storage recommendations to maintain product integrity. Typically, 1,4-Dihydroxyanthraquinone is sealed and stored in dry, cool, well-ventilated areas. Proper packaging, such as 25kg drums or bags, is employed to protect the material during transit. For those seeking a reliable source of this chemical intermediate, our expertise in manufacturing and dedication to quality assurance make us an ideal partner.
