2-Aminoanthraquinone
CAS Number: 117-79-3
2-Aminoanthraquinone is the 2-position isomer of aminoanthraquinone, serving as an intermediate for anthraquinone-based acid dyes and reactive dyes with blue and grey shades for protein and polyamide fibers. Its amino group at position 2 confers distinct electronic and steric properties compared to the 1-isomer, enabling different dye hue profiles. Chemzip supplies 2-aminoanthraquinone for specialty dye and organic pigment synthesis.
