1 4-Dihydroxyanthraquinone CAS 81-64-1

① Acts 1 4-Dihydroxyanthraquinone as a core dye intermediate for synthesizing disperse, vat and acid dyes, used for polyester/textile dyeing with excellent color fastness and orange–violet shade stability.

② Serves 1 4-Dihydroxyanthraquinone CAS 81-64-1 as a building block for manufacturing solvent dyes (Solvent Orange 86) for coloring gasoline, heating oils and plastics with vivid and stable hues.

③ Functions as a fine chemical raw material for preparing pharmaceutical intermediates and organic redox materials in energy storage due to dual active hydroxyl groups.

Store 1 4-Dihydroxyanthraquinone CAS 81-64-1 at 5-25℃ in sealed amber glass/HDPE drums in a cool, dry, dark well-ventilated area, away from open fire, strong oxidants, reducing agents and strong alkalis. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use to avoid moisture absorption, keep away from direct sunlight and high temperature. Dispose via licensed hazardous waste channels, transport as non-hazardous solid, no special inhibitor needed.

1 4-Dihydroxyanthraquinone CAS 81-64-1 is a low-toxic orange crystalline solid with outstanding thermal and chemical stability, non-flammable and no self-polymerization risk under normal storage.

1 4-Dihydroxyanthraquinone has dual active hydroxyl groups for etherification, esterification and condensation reactions; anthraquinone backbone ensures high light/wash fastness; high purity (≥99%) guarantees consistent dye shade and high synthesis yield, cost-effective for large-scale dye and fine chemical production.
