Used primarily as an intermediate in the synthesis of dyes and pigments, especially for high-performance pigments with excellent light and heat stability. It also serves in the production of certain fungicides and agrochemicals due to its chlorinated aromatic structure, which imparts biocidal activity. Its derivatives are explored in specialty polymers and flame retardants where thermal resistance and chemical durability are required. Limited use in research for developing chlorine-rich compounds with potential antimicrobial properties. Handling requires caution due to toxicity and environmental persistence.
