In the vast realm of organic chemistry, certain compounds serve as indispensable linchpins for major industrial processes. 2-Ethyl Anthraquinone (2-EAQ), identified by its CAS number 84-51-5, is one such compound. This pale yellow solid, often found in flake or powder form, is a vital intermediate with significant applications, most notably in the production of hydrogen peroxide and the synthesis of various dyes. Understanding its chemical properties and industrial significance is key for procurement managers and R&D scientists.

Chemical Profile of 2-Ethyl Anthraquinone

The molecular formula for 2-Ethyl Anthraquinone is C16H12O2, with a molecular weight of 236.27 g/mol. Its defining characteristics include a melting point typically ranging between 108-111°C. Chemically, it is stable under recommended storage conditions and is generally insoluble in water but soluble in organic solvents like benzene. These properties make it suitable for use in solution-based industrial processes.

Key Specifications for Industrial Use

For its critical roles in manufacturing, 2-EAQ is subject to stringent quality specifications. A high purity level, typically ≥99.0%, is essential. Critical parameters that buyers should look for from their hydrogen peroxide intermediate manufacturer or dye intermediate supplier include:

  • Appearance: Pale yellow flake or powder.
  • Purity (Assay): ≥99.0%
  • Melting Point: ≥107.0°C (initial melting point of dry basis).
  • Benzene Insoluble Matter: ≤0.05%. This low limit ensures minimal contamination in reaction mixtures.
  • Moisture Content: ≤0.20%. Water can interfere with certain reactions.
  • Impurity Limits: Controlled levels of iron (≤5 mg/kg), chlorine (≤10 mg/kg), and sulfur (≤10 mg/kg) are also crucial for process integrity.

Industrial Applications: More Than Just H2O2

While its role in hydrogen peroxide production is paramount, 2-EAQ's utility extends further:

  • Hydrogen Peroxide Production: It is a cornerstone of the anthraquinone process, providing the cyclic mechanism for H2O2 synthesis.
  • Dye Synthesis: It serves as an intermediate for reducing dyes, dispersed dyes, and reactive dyes, contributing to their chromophoric properties and application performance.
  • Organic Synthesis: 2-EAQ is a versatile building block in broader organic synthesis for creating specialized chemicals, functional materials, and potentially photoactive compounds. For instance, it can act as a photoinitiator for crosslinking or degradation of polyethylene.
