For procurement professionals and R&D chemists in industries that utilize chemical intermediates, a thorough understanding of product specifications is crucial for successful sourcing and application. Anthraquinone, identified by CAS number 84-65-1, is a critical compound widely employed in the paper industry as a catalyst and in the synthesis of various dyestuffs. NINGBO INNO PHARMCHEM CO.,LTD., a dedicated chemical manufacturer and supplier from China, provides this essential guide to help industrial buyers make informed purchasing decisions.

Product Identification: The primary identifier for this compound is its CAS number, 84-65-1. Additionally, it is known by synonyms such as 9,10-Dioxoanthracene and its IUPAC name is anthracene-9,10-dione. Its molecular formula is C14H8O2, and its molecular weight is approximately 208.21 g/mol.

Appearance and Physical Form: Industrial buyers often rely on visual cues for initial product assessment. Anthraquinone typically presents as a yellow or light grey to grayish green powder. This specific appearance is consistent across high-quality batches. For researchers, its crystalline nature is also noted; it can appear as yellow rhombic needles or slender monoclinic prisms depending on the purification method.

Purity Standards: The functional efficacy of Anthraquinone is directly linked to its purity. For most industrial applications, a minimum purity of 97% is considered standard. Higher purity grades may be available for specialized research or niche applications. As a conscientious supplier, NINGBO INNO PHARMCHEM CO.,LTD. ensures that our Anthraquinone consistently meets or exceeds this critical 97% purity threshold. This commitment guarantees reliable performance in your manufacturing processes.

Key Performance Parameters:

  • Melting Point: Anthraquinone has a high melting point, typically in the range of 283-288°C, indicating its robust thermal stability.
  • Ash Content: Industrial grades usually specify a low ash content, often ≤0.5%, signifying minimal inorganic impurities.
  • Loss on Drying: Similarly, a low loss on drying (≤0.5%) indicates minimal moisture content, which is important for storage stability and accurate weighing in formulations.

Packaging and Minimum Order: For industrial distribution, Anthraquinone is commonly supplied in 25 kg bags, facilitating ease of handling and storage in manufacturing environments. The minimum order quantity is also an important factor for procurement planning, often set at 25 kg to align with standard packaging. As your reliable chemical supplier, we cater to bulk orders, ensuring you can procure the quantities needed for your production runs.
