For procurement professionals and R&D scientists in the chemical industry, sourcing high-quality raw materials is a continuous challenge. Quinizarin, also known as 1,4-Dihydroxyanthraquinone and bearing the CAS number 81-64-1, is a compound that demands careful consideration due to its critical role in dye manufacturing and organic synthesis. As a leading supplier and manufacturer of this essential chemical, we aim to provide a practical guide to help buyers navigate the sourcing process, ensuring they secure both quality and value.

The first step in sourcing Quinizarin is to understand its essential specifications. Typically available in two main grades – 96% crude and 99% fine – the choice depends on the intended application. For high-end dye production or sensitive chemical synthesis, the 99% purity grade is often preferred. Understanding the distinction between these grades and verifying the supplier's quality control measures is crucial. As a reputable manufacturer, we adhere to strict testing protocols to ensure our 1,4-dihydroxyanthraquinone consistently meets these purity standards.

Beyond purity, a key consideration is the supplier's reliability and origin. Manufacturers based in China, such as ourselves, often offer competitive pricing due to efficient production processes and economies of scale. When you are looking to buy 1,4-dihydroxyanthraquinone, comparing the quinizarin price from different reputable suppliers is a wise strategy. However, it's imperative to balance cost with quality assurance. A slightly higher price for a product from a trusted manufacturer with proven quality control can prevent costly production issues down the line.

When evaluating suppliers, consider their capacity and export experience. A manufacturer with a substantial monthly output and a track record of exporting to major markets like the US and Germany indicates robustness and adherence to international standards. This is particularly important for large-volume procurement. Furthermore, the availability of technical documentation, such as Safety Data Sheets (SDS) and Certificates of Analysis (COA), is non-negotiable. These documents provide critical information about the product's safety, handling, and quality, which are essential for compliance and process management.

The applications of Quinizarin are diverse, ranging from its use as an intermediate for VAT, disperse, and reactive dyes to its function in industrial coloring of plastics and resins, and as a building block in organic synthesis. Knowing your specific application will help you determine the precise grade and quantity required.
