High Purity Anthraquinone Dye Intermediates 1-Aminoanthraquinone 98.5%

1-Aminoanthraquinone, with CAS No. 82-45-1 and commonly referred to as alpha-Aminoanthraquinone, is a high-purity aromatic amine that serves as a fundamental building block for the synthesis of a vast array of anthraquinone dyes and organic pigments. Supplied as a red-orange crystalline powder with a minimum assay of 98.5%, this compound is the direct reduction product of 1-Nitroanthraquinone and is indispensable for dye manufacturers aiming to produce colorants with outstanding light fastness, weather resistance, and thermal stability.

• High Purity Standard: Minimum 98.5% assay (by HPLC) ensures maximum conversion efficiency and minimizes purification requirements
• Distinctive Physical Form: Red to orange-red crystalline powder with characteristic melting point for easy visual inspection
• Clear Chemical Traceability: Fully identified with CAS 82-45-1 and synonym alpha-Aminoanthraquinone
• Stable Industrial Supply: Manufactured under strict process controls with consistent quality and quantity

1-Aminoanthraquinone is primarily utilized as a dye intermediate for producing high-performance dyes including vat dyes, disperse dyes, acid dyes, and reactive dyes. These are prized for exceptional durability on textiles, leather, and plastics.

A particularly important application is in the production of organic pigments, serving as a key precursor for anthraquinone-based red and blue pigments used in automotive coatings, high-grade printing inks, engineering plastics, and architectural paints where resistance to light and solvents is critical.

Beyond colorants, it also serves as a valuable intermediate for manufacturing pharmaceutical compounds, UV absorbers, and photo-sensitive materials.
