This article delves into its key characteristics, safety considerations, and diverse application potential, aiming to equip procurement managers and research scientists with essential knowledge for sourcing and utilizing this chemical.

Physico-Chemical Profile of 1,4-Dichloroanthraquinone

1,4-Dichloroanthraquinone, with the molecular formula C14H6Cl2O2 and a molecular weight of 277.1 g/mol, presents itself typically as light yellow to brown powder crystals. Its melting point is in the range of 187-189 °C, indicating it is a solid at room temperature. While sparingly soluble in common solvents like ethanol and ether, it exhibits better solubility in nitrobenzene, pyridine, hot benzene, and acetic acid. Its chemical structure, an anthraquinone backbone with chlorine substituents, dictates its reactivity and thus its primary uses.

Key Applications and Use Cases

The primary application for 1,4-Dichloroanthraquinone is as a dye intermediate. It is instrumental in the synthesis of anthraquinone disperse dyes and vat dyes, which are highly valued for imparting bright, stable colors to fabrics. The compound's structure allows for modifications that lead to excellent lightfastness and wash fastness in the final dyes.

Beyond its role in coloration, 1,4-Dichloroanthraquinone also serves as a valuable building block in general organic synthesis. This makes it a sought-after chemical for researchers developing new pharmaceuticals or advanced functional materials. Its potential use as a photosensitizer or electron acceptor in photochemical research further broadens its applicability in material science and specialized chemical studies. When sourcing, professionals often search for 'CAS 602-25-5 dye intermediate' or 'buy organic synthesis chemical'.

Safety and Handling Considerations

According to available safety data, 1,4-Dichloroanthraquinone is classified as an irritant (Xi) and carries hazard statements such as H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation). Consequently, appropriate safety precautions are essential. When handling this chemical, it is crucial to wear suitable protective clothing, including gloves and eye protection, and ensure adequate ventilation to avoid inhalation. Storage should be in a dry place, away from light, and containers should be kept sealed.

Sourcing a Quality Product

For industries relying on precise chemical formulations, securing high-purity 1,4-Dichloroanthraquinone is non-negotiable. As a buyer, it's essential to partner with manufacturers and suppliers who can guarantee a high assay (≥98%) and provide robust documentation, including Safety Data Sheets (SDS) and Certificates of Analysis (CoAs). Companies often look to established suppliers in China for competitive pricing and consistent availability. When you decide to purchase, inquire about packaging options, such as 25kg barrels, and ensure your supplier can meet your specific quantity requirements. A responsive supplier who can provide technical data readily will be an invaluable asset.

By understanding the fundamental chemical properties and applications of 1,4-Dichloroanthraquinone, and by prioritizing quality sourcing, businesses can effectively leverage this compound for advanced dye manufacturing and innovative chemical synthesis projects.
