Understanding the core chemistry of industrial intermediates is fundamental for R&D scientists and formulators. 2-Ethyl Anthraquinone (2-EAQ), identified by CAS number 84-51-5, is a derivative of anthraquinone that possesses a unique set of physical and chemical properties making it indispensable in several key industrial processes. As a significant supplier of this compound, we aim to provide a clear overview of its chemical identity and industrial importance.

The molecular formula for 2-Ethyl Anthraquinone is C₁₆H₁₂O₂, with a molecular weight of approximately 236.27 g/mol. Its chemical structure features an anthraquinone core with an ethyl group attached at the 2-position. This specific molecular arrangement dictates its behavior in chemical reactions and its physical characteristics.

Physically, 2-EAQ is described as a light yellow flake, a solid at room temperature with a melting point typically ranging from 108-111°C. This solid form, usually packed in 25 kg bags, facilitates handling and storage for industrial users. Its insolubility in water is a common characteristic for many organic intermediates of this size and polarity.

The industrial significance of 2-Ethyl Anthraquinone is overwhelmingly tied to its role in the anthraquinone process for hydrogen peroxide production. In this process, 2-EAQ acts as the primary carrier of hydrogen. It is hydrogenated to 2-Ethylanthrahydroquinone (EAHQ), which is then oxidized by molecular oxygen to yield hydrogen peroxide and regenerate the original 2-EAQ. This cyclical mechanism is highly efficient and forms the backbone of industrial H₂O₂ manufacturing.

Beyond this major application, the chemical reactivity of the anthraquinone structure allows 2-EAQ to function as a dye intermediate and a catalyst in photopolymerization. As a photoinitiator or sensitizer, it plays a role in the curing of resins and films, contributing to advancements in materials science and coatings. For those looking to buy chemicals for these applications, understanding the purity and consistency offered by manufacturers is key.
