For procurement managers and R&D professionals in the chemical industry, sourcing high-quality intermediates is paramount. One such crucial compound is 1,4-Dihydroxyanthraquinone, widely recognized by its common names Quinizarin and Solvent Orange 86, with CAS number 81-64-1. This orange to deep orange crystalline powder is a cornerstone in the synthesis of various dyes and finds extensive use in industrial coloring applications. Understanding its properties, applications, and where to buy it is essential for streamlined operations and product innovation.

The Significance of 1,4-Dihydroxyanthraquinone in Dye Production

As an anthraquinone derivative, 1,4-Dihydroxyanthraquinone is highly valued as an intermediate for producing VAT dyes, disperse dyes, and reactive dyes. These dye classes are vital for achieving vibrant, long-lasting colors on textiles, offering excellent lightfastness and wash fastness. The molecular structure of Quinizarin allows it to be readily modified through processes like sulfonation and amination to create a wide spectrum of colorants, including specific shades like disperse blue HSR, disperse blue 5R, and acid anthraquinone blue R. For manufacturers focusing on high-performance textile dyes, securing a consistent supply of high-purity 1,4-Dihydroxyanthraquinone is a strategic imperative. Inquiry about bulk purchase options and pricing from reputable manufacturers in China can lead to significant cost savings.

Industrial Coloring Applications Beyond Textiles

The utility of 1,4-Dihydroxyanthraquinone extends beyond the textile industry. Its stable color properties make it an excellent choice for coloring various plastics, resins, and their finished products. This includes applications in automotive components, consumer goods, and packaging, where consistent coloration is key. Furthermore, Quinizarin is used for the coloration of industrial oils and fuels, aiding in product identification and differentiation. Companies seeking to buy 1,4-Dihydroxyanthraquinone for these industrial coloring needs will find its performance reliable and its availability from Chinese suppliers robust.

Sourcing Strategies: Finding the Right Supplier for Quinizarin

When looking to purchase 1,4-Dihydroxyanthraquinone, especially in bulk quantities, identifying a dependable manufacturer and supplier is crucial. Key considerations include product purity (typically 96% or 99% grades are available), consistent batch quality, competitive pricing, and efficient delivery. Many manufacturers in China specialize in these intermediates and can offer Certificates of Analysis (COA), Material Safety Data Sheets (MSDS), and responsive customer service. To find the best price for Solvent Orange 86 or to request a sample for testing, engaging with suppliers through their online platforms or direct inquiries is recommended. Purchasing directly from a manufacturer often provides the most advantageous price points.

In conclusion, 1,4-Dihydroxyanthraquinone (CAS 81-64-1) is a versatile and indispensable chemical intermediate. Whether your focus is on advanced dye synthesis or industrial coloring applications, understanding its properties and sourcing it effectively from reliable manufacturers in China will empower your procurement and R&D efforts.
