1-Aminoanthraquinone (CAS 82-45-1) stands as a cornerstone in the synthesis of anthraquinone dyes, a class of colorants celebrated for their exceptional color fastness, brilliance, and stability. For chemical formulators and R&D scientists, understanding the multifaceted properties and application potential of this organic intermediate is key to developing high-performance color solutions. This article delves into what makes 1-Aminoanthraquinone a vital component in modern dye manufacturing.

The chemical structure of 1-Aminoanthraquinone, featuring an amino group attached to the anthraquinone core, grants it unique reactivity and chromophoric properties. Typically appearing as a red flash needle crystal or crystalline powder, it exhibits solubility in common organic solvents such as ethanol, ether, and glacial acetic acid, while being largely insoluble in water. This solubility profile is advantageous for various synthesis pathways and application methods in dye formulations. Its relatively high melting point (253-255°C) contributes to the thermal stability of the dyes produced from it.

The primary utility of 1-Aminoanthraquinone lies in its role as an intermediate for an extensive range of dyes. It is indispensable for producing vat dyes like reduced 2G, reduced olive green B, and olive R, as well as disperse dyes such as dispersed red 3B, and reactive dyes like brilliant blue KN-R. These dyes find widespread application in coloring textiles, paper, and plastics, where demanding performance criteria, such as resistance to light, washing, and chemicals, are essential. Manufacturers who buy 1-Aminoanthraquinone ensure they have a reliable source for creating these high-quality colorants.

Beyond its dominant role in the dye industry, 1-Aminoanthraquinone also finds niche applications in pharmaceutical synthesis and as a reagent in analytical chemistry. Its ability to intercalate with DNA has led to its investigation in certain therapeutic contexts, and its specific chemical properties make it useful for detecting or quantifying particular substances in laboratory settings. Researchers seeking these specialized applications can source high-purity 1-Aminoanthraquinone from reputable chemical suppliers.

In summary, 1-Aminoanthraquinone (CAS 82-45-1) is a critical intermediate that empowers the creation of vibrant, durable colors. Its versatile properties and broad applicability make it a sought-after material for dye manufacturers and chemical innovators worldwide. When planning your procurement, consider reliable manufacturers and suppliers who can guarantee the purity and consistent supply needed for your formulation success.
