Description

Heptadecylbenzenesulphonic 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 chain length, which imparts specific emulsifying, wetting, and detergent properties not found in shorter-chain homologues. This compound is essential for formulators and manufacturers in the industrial cleaning, agrochemical, and specialty chemical synthesis sectors seeking tailored performance characteristics.

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.
• Emulsifying and dispersing agent in agrochemical formulations such as pesticides and herbicides.
• Acid catalyst in specific organic synthesis and esterification reactions.
• Additive in petroleum industry applications, including demulsifiers and drilling fluid components.
• Precursor for sulfonate salts used in lubricant and grease formulations.
• Research and development chemical for novel surfactant structures in academic and industrial labs.

Quality Control

Our Heptadecylbenzenesulphonic Acid is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with every shipment to guarantee supply reliability and specification compliance for your production processes.

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 mixture; containers must be kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
