Description

2,4-Dichlorobenzenesulfonic Acid is a versatile organosulfur compound that serves as a critical synthetic intermediate and functional additive. Its value lies in its dual functionality, combining the reactivity of a strong sulfonic acid with the directing and modifying effects of the dichlorinated aromatic ring. This product is essential for manufacturers in the agrochemical, pharmaceutical, and specialty chemical industries seeking to build complex molecular architectures or impart specific properties to their formulations.

Application

• Agrochemical Synthesis: A key intermediate in the production of herbicides, fungicides, and plant growth regulators, leveraging its aromatic sulfonic acid structure.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a benzenesulfonic acid moiety.
• Dye and Pigment Manufacturing: Acts as a precursor or sulfonating agent in the synthesis of various dyes and organic pigments.
• Polymer Modification: Employed as a monomer or additive to introduce sulfonic acid groups into polymers, enhancing properties like hydrophilicity or ion-exchange capacity.
• Catalysis and Chemical Synthesis: Serves as an acid catalyst or a building block in organic synthesis for creating more complex sulfonated compounds.
• Surfactant and Detergent Industry: Can be used as a raw material for producing specialized anionic surfactants.

Quality Control

Our 2,4-Dichlorobenzenesulfonic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and consistency. A comprehensive Certificate of Analysis (COA) detailing the results of tests such as assay, impurity profile, and physical characteristics is provided with each shipment to guarantee reliable performance in your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Recommended storage temperature is between 15°C and 25°C.
