Key Properties & Uses
It is an aromatic ketone derivative of anthraquinone, where a chlorine atom is substituted at the 1-position of the anthraquinone core.
Uses include:
Intermediate in the synthesis of dyes and pigments (especially anthraquinone-based dyes).
Sometimes used in research chemistry for synthesizing other anthraquinone derivatives.
It can be prepared by chlorination reactions starting from anthraquinone-1-sulfonic acid derivatives.
Safety & Handling
Hazards: Causes eye irritation (H320) and is harmful to aquatic life with long-lasting effects (H412).
Precautions: Avoid release to the environment, wash skin after handling, wear eye protection, and dispose of properly.
