CAS 82-45-1 1-Aminoanthraquinone
Overview
1-Aminoanthraquinone (also known as 1-amino-9,10-anthraquinone; AAQ; CAS 82-45-3; C₁₄H₉NO₂) is an anthraquinone dye intermediate widely used in the production of red to bluish-red dyes for textiles, leather, plastics, and inks. It is commonly employed in disperse, solvent, and vat dye systems thanks to its strong coloring power, excellent lightfastness, and high thermal stability on polyester and related substrates.
