For businesses in the dye and pigment industry, securing a consistent supply of high-quality intermediates is paramount. One such critical compound is 1,4-Dihydroxyanthraquinone, commonly known as Quinizarin or Solvent Orange 86. Its unique chemical structure makes it an indispensable component in the creation of a wide spectrum of vibrant and durable dyes, as well as for various industrial coloring applications. This article serves as a practical guide for procurement managers and R&D professionals looking to buy Quinizarin, focusing on key considerations when sourcing this essential chemical from a reliable manufacturer.

Understanding the significance of 1,4-Dihydroxyanthraquinone begins with its chemical properties and specifications. Typically supplied as an orange to deep orange powder, its purity is a critical factor. Reputable suppliers, particularly those based in China, often provide Quinizarin with an assay of 99% or higher, meeting stringent standards such as USP, BP, EP, and FCC. When you purchase this intermediate, ensuring such high purity guarantees predictable performance in downstream applications, from complex dye synthesis to uniform coloring of plastics and resins. The CAS number 81-64-1 is your key identifier when searching for this product.

The primary application driving the demand for 1,4-Dihydroxyanthraquinone is its role as a dye intermediate. It is fundamental in the manufacturing of VAT dyes, disperse dyes, and reactive dyes. Specifically, it is used to produce well-known dyes such as Disperse Blue HSR, Disperse Blue 5R, Acid Anthraquinone Blue R, and Disperse Brown GL (C.I.58050). For manufacturers of textile dyes, sourcing Quinizarin with consistent quality is vital for achieving desired color shades and fastness properties. When inquiring about price, consider the overall value delivered by a manufacturer committed to quality control.

Beyond textile applications, Quinizarin finds significant use in industrial coloring. Its ability to impart color to plastics, resins, and various oils makes it a versatile additive. Procurement managers looking to buy Solvent Orange 86 for these purposes will appreciate suppliers who can offer both high purity and competitive pricing. The stability and vibrant hue it provides are crucial for product identification and aesthetic appeal in a wide range of manufactured goods.

When sourcing from a manufacturer, it’s essential to evaluate their production capacity, quality certifications (like ISO), and their ability to provide comprehensive documentation, including TDS and COA. For businesses aiming to buy 1,4-Dihydroxyanthraquinone in bulk, establishing a relationship with a dependable supplier based in China can offer significant advantages in terms of cost-effectiveness and supply chain reliability. A proactive approach, including requesting samples and obtaining quotes from multiple suppliers, will help secure the best partnership. Remember, a prompt response from a potential supplier to your inquiries about product availability, lead times, and pricing is often an indicator of their professionalism and customer service.

In conclusion, 1,4-Dihydroxyanthraquinone is a cornerstone chemical for many industries. By understanding its specifications, applications, and the importance of partnering with a reliable manufacturer and supplier, businesses can ensure they are procuring a high-quality intermediate that contributes to the success of their final products. Investing in a trusted source for Quinizarin is an investment in the quality and vibrancy of your color solutions.
