In the vast realm of industrial chemistry, certain compounds stand out due to their indispensable roles as intermediates. 3,4-Dichloroaniline (CAS 95-76-1) is one such compound, serving as a critical building block in the synthesis of a range of high-value products, primarily in the agrochemical and dye sectors.

Chemical and Physical Properties of 3,4-Dichloroaniline

3,4-Dichloroaniline, with the molecular formula C6H5Cl2N and CAS number 95-76-1, is characterized by its physical form: white flaky crystals. Its solubility profile is notable; it dissolves readily in alcohol and ether but shows minimal solubility in water. This characteristic influences its handling and application in various chemical processes. The compound's stability is generally good, though it can darken upon prolonged exposure to heat, light, and air. It is classified as a combustible substance and requires careful handling to avoid contact with incompatible materials such as strong oxidizing agents and acids.

Synthesis and Manufacturing Insights

The industrial production of 3,4-Dichloroaniline typically involves the catalytic hydrogenation of 3,4-dichloronitrobenzene. This process utilizes noble metal catalysts under pressure. Manufacturers often incorporate specific additives during production to prevent dehalogenation, a process that can compromise product integrity. Furthermore, the reactors used in its synthesis are often fabricated from special steel alloys to mitigate corrosion. For businesses looking to buy 3,4-Dichloroaniline, understanding these manufacturing nuances highlights the importance of sourcing from experienced producers who maintain strict process controls and quality assurance.

Industrial Applications: Pesticides and Dyes

The utility of 3,4-Dichloroaniline is primarily concentrated in two key industrial areas:

  • Pesticides: It is a foundational intermediate in the manufacturing of herbicides like propanil and linuron. These herbicides are vital for modern agriculture, ensuring crop protection and productivity.
  • Dyes: The compound is also a significant intermediate in the production of azo dyes. Its chemical structure is conducive to forming the chromophores responsible for color, making it valuable for the textile and other coloration industries.

Sourcing Strategy for Procurement Managers

Procurement managers seeking a reliable supply of 3,4-Dichloroaniline often turn to Chinese manufacturers for competitive pricing and quality assurance. When inquiring about 3,4-dichloroaniline price and availability, it is essential to specify the required purity (e.g., ≥99%) and packaging (e.g., 25kg drums). Engaging directly with manufacturers can streamline the purchasing process, ensuring access to technical support and consistent product availability.

3,4-Dichloroaniline remains a cornerstone chemical intermediate, underpinning critical industries. A thorough understanding of its properties and applications, coupled with a strategic sourcing approach, is key for any professional in the field.
