1. Key Raw Material for Chemical Synthesis
• Pesticide Intermediates
One of its main uses is in the synthesis of herbicide precursors such as 3,4-dichloroaniline.
• Pharmaceutical and Dye Intermediates
Used in the production of intermediates for pharmaceuticals (such as long-acting sulfonamides and chlorhexidine) and dyes (such as vat blue).

2. High-Performance Solvent
• Solvents for Resins, Asphalt, and Rubber
Due to its strong solvency and slow evaporation characteristics, it is used in paints, varnishes, and industrial degreasers.
• Polymer Processing Solvent
Used as a solvent in the production of polyurethane raw materials (TDI) and as a diluent for epoxy resins.
• Metal Parts Degreasing and Cleaning Agent
Used to remove carbon deposits from engine parts, metal surface coatings, and sulfur from illuminating gas.

3. Materials and High-Tech Applications
• Advanced Materials Research (e.g., Fullerenes)
It is an excellent solvent for fullerene (C60) and other nanocarbon materials.
• Organic Electronic Device Fabrication
Used in the processing of active layer materials in organic solar cells (OPV).

4. Industrial and Special Uses
• Insecticides and Preservatives
Used directly or as a component in insecticides for termites, locusts, etc., as well as fumigants and preservatives.
• Heat Exchange Medium
Due to its stable physicochemical properties, it can be used as an industrial coolant or high-temperature organic heat carrier.
• Analytical Standard
Used as an analytical standard for detecting organic pollutants in water and soil in environmental monitoring.
