Description

Pentadecylbenzenesulphonic Acid is a high-purity, long-chain alkylbenzene sulfonic acid derivative, serving as a critical intermediate and surfactant precursor. Its value lies in its unique hydrophobic-hydrophilic balance, making it essential for formulating specialized detergents, emulsifiers, and corrosion inhibitors. This product is particularly needed by manufacturers in the industrial cleaning, agrochemical, and lubricant additive sectors seeking consistent performance and reliable supply.

Application

• Primary raw material for the synthesis of specialized anionic surfactants and emulsifiers.
• Key intermediate in the production of industrial and institutional (I&I) cleaning formulations.
• Corrosion inhibitor component in metalworking fluids and lubricant additive packages.
• Emulsifying agent and wetting agent in agrochemical formulations such as pesticides and herbicides.
• Acid catalyst in specific organic synthesis reactions within fine chemical manufacturing.
• Dispersant and stabilizer in the production of pigments, dyes, and coatings.

Quality Control

Our Pentadecylbenzenesulphonic Acid is manufactured under a rigorous quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and 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; containers must be kept tightly sealed to prevent absorption of atmospheric moisture and corrosion. Keep away from incompatible materials such as strong bases and oxidizing agents.
