Description

Diisopropylbenzenesulphonic Acid is a specialized organic sulfonic acid derivative, valued for its strong acidity and surfactant properties. This compound serves as a critical intermediate and catalyst in advanced organic synthesis and industrial formulations. It is essential for manufacturers in the chemical, agrochemical, and specialty materials sectors seeking efficient sulfonation and acid-catalyzed reactions.

Application

• Chemical Intermediate: A key building block in the synthesis of more complex sulfonated compounds, dyes, and pigments.
• Catalyst: Used as an acid catalyst in esterification, alkylation, and other organic transformations requiring strong Brønsted acidity.
• Surfactant & Detergent Precursor: Acts as a precursor for the manufacture of specialized anionic surfactants and detergent formulations.
• Agrochemical Synthesis: Employed in the production of certain herbicides, pesticides, and plant growth regulators.
• Polymer & Resin Modification: Used to introduce sulfonic acid groups into polymers, enhancing properties like hydrophilicity or ion-exchange capacity.
• Electroplating & Metal Treatment: Functions as an additive in plating baths and surface treatment solutions.
• Research & Development: Serves as a reagent in pharmaceutical and material science research laboratories.

Quality Control

Our Diisopropylbenzenesulphonic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; containers must be kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
