In the vibrant world of color, chemical intermediates play a foundational role, dictating the quality, shade, and longevity of dyes. Quinizarin, with CAS number 81-64-1, is a prominent example of such an essential chemical. This article explores the critical function of Quinizarin as a dye intermediate, detailing its chemical characteristics, synthesis considerations, and its impact on the final performance of colored materials. For businesses in the textile, printing, and coatings industries, understanding the sourcing and application of this compound is key.

Quinizarin, chemically known as 1,4-Dihydroxyanthraquinone, is an organic compound characterized by its distinctive orange to red crystalline powder appearance. Its molecular structure (C14H8O4) is central to its utility in dye synthesis. The anthraquinone core, coupled with hydroxyl groups at specific positions, provides a robust platform for developing a wide spectrum of colors. The purity of Quinizarin is paramount; manufacturers typically strive for levels of 97% or higher to ensure consistent color output and prevent undesirable reactions during the dyeing process.

The manufacturing of Quinizarin involves complex chemical processes that require stringent quality control to achieve the desired purity. As a significant chemical intermediate, its demand is driven by the global textile industry, as well as manufacturers of pigments and inks. For companies looking to purchase Quinizarin, securing a reliable supplier who can consistently deliver high-quality material is crucial for maintaining product integrity and production efficiency. Manufacturers in China are often key sources for this compound, offering competitive pricing and considerable production capacity.

The application of Quinizarin extends to creating dyes with excellent fastness properties, meaning the color resists fading from light, washing, and rubbing. This durability is highly valued in applications ranging from apparel to automotive coatings. Furthermore, Quinizarin itself has been a subject of research for its biological properties, including potential anti-cancer effects, though its primary industrial role remains in colorant production. Businesses seeking to buy Quinizarin should look for suppliers who can provide comprehensive technical data and support, ensuring that their procurement decisions align with their production goals and quality requirements.
