Solvents are fundamental to countless industrial processes, facilitating reactions, dissolving materials, and enabling efficient extraction and purification. Among the array of industrial solvents, 1,2,4-Trichlorobenzene (CAS: 120-82-1) holds a significant position due to its unique chemical properties and versatility.

Understanding 1,2,4-Trichlorobenzene as a Solvent

1,2,4-Trichlorobenzene is an organochlorine compound that exists as a colorless transparent liquid at room temperature, with a melting point of 16°C. Its relatively high boiling point (211.4°C) and strong solvency make it suitable for applications where other common solvents might fail. These characteristics allow it to dissolve a wide range of organic compounds, including certain polymers that are otherwise difficult to process. Its density of approximately 1.4 g/cm³ means it is denser than water, which can be a factor in separation processes.

Beyond Solvency: Its Role as an Intermediate

While its solvent capabilities are notable, 1,2,4-Trichlorobenzene is perhaps more critically recognized as a chemical intermediate. Its molecular structure (C6H3Cl3) makes it a key precursor in the synthesis of important agrochemicals such as the herbicide Dicamba and the acaricide Tetradifon. The high purity (≥99.0%) often required for these applications underscores the importance of sourcing from manufacturers who maintain stringent quality control.

Procurement Insights for Industry Professionals

For R&D scientists and procurement managers, understanding the specifications of 1,2,4-Trichlorobenzene is vital:

  • Appearance: Colorless transparent liquid
  • Assay: Typically ≥99.0%
  • CAS Number: 120-82-1
  • Applications: Intermediate for Dicamba/Tetradifon, solvent, dye carrier
  • Storage: Cool, ventilated place, commonly in 200 kg drums.

When looking to buy 1,2,4-Trichlorobenzene, it is beneficial to engage with experienced chemical manufacturers, particularly those in China, who can offer competitive pricing and reliable supply chains. Requesting quotes and product samples is a standard practice to ensure the material meets the exacting standards for your specific application, whether it's for solvent use or as a crucial intermediate.

The multifaceted role of 1,2,4-Trichlorobenzene highlights the importance of specialized chemicals in driving industrial innovation and production efficiency. By understanding its properties and sourcing strategies, businesses can leverage this compound for optimal results.
