Description

Sulfonic Acids CAS NO 308076-40-6 represent a versatile class of organic compounds characterized by the presence of a sulfonic acid functional group, which imparts strong acidity and excellent surfactant properties. These compounds are critical as intermediates and active ingredients in the synthesis of high-performance detergents, emulsifiers, and catalysts. They are essential for manufacturers in the detergent, agrochemical, pharmaceutical, and specialty chemical industries seeking to enhance product efficacy and stability.

Application

• Detergent & Surfactant Manufacturing: Primary raw material for producing linear alkylbenzene sulfonates (LAS) and other anionic surfactants for industrial and household cleaners.
• Chemical Synthesis Intermediate: Key building block in organic synthesis for creating dyes, pigments, and pharmaceutical active ingredients.
• Catalyst & Acidulant: Used as a strong acid catalyst in esterification, alkylation, and other industrial chemical processes.
• Agrochemical Formulations: Component in the production of herbicides, pesticides, and fungicides, improving solubility and delivery.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery formulations as demulsifiers and wetting agents.
• Textile & Leather Processing: Acts as a levelling agent, dyeing assistant, and tanning agent in textile and leather treatment.
• Polymer & Resin Modification: Used to modify polymers for improved solubility, adhesion, and ion-exchange properties.

Quality Control

Our Sulfonic Acids are produced under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot is analyzed for critical parameters including acid value, active matter content, and color. A comprehensive Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

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