While the primary industrial application of 2-Ethyl Anthraquinone (2-EAQ, CAS 84-51-5) is undoubtedly its role as a crucial catalyst in the anthraquinone process for hydrogen peroxide (H2O2) production, its chemical versatility extends far beyond this single use. As a derivative of anthraquinone, 2-EAQ possesses a unique molecular structure that lends itself to a variety of valuable applications in organic synthesis, making it a compound of significant interest across multiple sectors of the chemical industry.

One of the prominent secondary applications for 2-EAQ lies in the realm of dyes and pigments. The inherent chromophoric system of the anthraquinone core, modified by the ethyl substituent, allows 2-EAQ to serve as a building block or intermediate in the synthesis of complex coloring agents. These dyes can find use in textiles, inks, and coatings, contributing to the vibrant palette of modern manufacturing. The reactivity of the anthraquinone structure enables chemists to introduce further functional groups, tailoring the properties of the resulting dyes for specific performance requirements.

Furthermore, 2-EAQ is recognized for its utility in the pharmaceutical industry. It can function as a key intermediate in the multi-step synthesis of various active pharmaceutical ingredients (APIs) or related compounds. The specific structural features of 2-EAQ can be manipulated through established organic reactions to construct more complex molecular architectures that form the basis of therapeutic agents. The demand for high-purity 2-ethyl anthraquinone CAS 84-51-5 is thus driven not only by H2O2 production but also by the meticulous requirements of pharmaceutical manufacturing.

Emerging research also points to the potential of 2-EAQ in advanced material science, particularly in the field of photovoltaics and photosensitive materials. Its ability to absorb and interact with light makes it a candidate for use as a sensitizer or acceptor material in organic solar cells. Additionally, it is explored for applications in photosensitive resins, light-cured resins, and photodegradable mulch, underscoring its role in innovative technologies.
