In the realm of industrial coloring and chemical synthesis, certain intermediates prove indispensable due to their unique properties and broad applicability. 1,4-Dihydroxyanthraquinone, commonly known as Quinizarin or Solvent Orange 86, is one such compound. Its vibrant color and chemical reactivity make it a sought-after material for coloring various industrial products and serving as a precursor in more complex syntheses. For businesses needing to buy this versatile chemical, understanding its properties and how to source it effectively is key.

Chemically, 1,4-Dihydroxyanthraquinone (CAS 81-64-1) is an organic compound derived from anthraquinone. It presents as an orange to deep orange crystalline powder. Its molecular structure, featuring an anthraquinone backbone with two hydroxyl groups, is responsible for its chromophoric properties. This characteristic makes it highly suitable for applications where consistent and stable coloration is required. When considering a purchase, buyers often look for a high purity level, typically 99% or above, along with low moisture content and minimal impurities, to ensure optimal performance in their specific industrial coloring processes.

The industrial coloring applications for Quinizarin are quite varied. It is frequently used to impart color to plastics and resins, enhancing their aesthetic appeal and aiding in product identification. Manufacturers in the plastics industry often buy Solvent Orange 86 for its excellent thermal stability and compatibility with many polymer matrices. Beyond plastics, it is also employed in the coloration of oils, such as gasoline and heating fuels, serving as a marker for different grades or types of fuel.

The significance of 1,4-Dihydroxyanthraquinone extends beyond direct coloring; it is also a crucial intermediate in the synthesis of other dyes and pigments. It serves as a building block for various VAT, disperse, and reactive dyes used extensively in the textile industry. Its derivatives can also be used to create specialized pigments. For companies operating in these sectors, securing a reliable supply of high-quality Quinizarin from a trusted manufacturer is vital for maintaining product quality and production efficiency.

Sourcing 1,4-Dihydroxyanthraquinone from China offers many advantages, including competitive pricing and large-scale production capabilities. When looking to buy, it is advisable to partner with manufacturers who adhere to strict quality control standards and can provide comprehensive documentation such as COA and TDS. Understanding the typical specifications, like a 99.5% assay and low toluene intolerance, will help in evaluating potential suppliers. It is also beneficial to inquire about packaging options and logistics to ensure seamless integration into your supply chain.

In conclusion, 1,4-Dihydroxyanthraquinone is a valuable chemical for numerous industrial coloring applications. Its chemical properties, combined with its utility as a synthetic intermediate, make it a vital component for many manufacturing processes. By focusing on purity, quality certifications, and establishing strong relationships with reputable manufacturers and suppliers, businesses can efficiently procure this essential compound to meet their industrial coloring needs.
