Description

2-Heptadecyl-1H-Benzimidazolesulphonic Acid is a specialized organic acid derivative belonging to the benzimidazole chemical class. This compound is valued for its unique surfactant and corrosion-inhibiting properties derived from its long alkyl chain and heterocyclic sulfonic acid structure. It is primarily utilized in the formulation of high-performance industrial lubricants, metalworking fluids, and as a functional intermediate in specialty chemical synthesis for sectors demanding tailored surface activity and stability.

Application

• As a key corrosion inhibitor and additive in industrial lubricants and metalworking fluids.
• As a functional surfactant intermediate for synthesizing specialty chemicals with specific hydrophilic-lipophilic balance (HLB) requirements.
• In the formulation of anti-wear agents and extreme pressure (EP) additives for automotive and machinery lubricants.
• As a dispersant and stabilizer in various industrial fluid systems.
• In research and development for creating novel pharmaceutical intermediates or agrochemicals based on the benzimidazole core.
• Potential use as a coating additive to enhance adhesion and surface properties.

Quality Control

Our production of 2-Heptadecyl-1H-Benzimidazolesulphonic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure consistency and meet customer specifications. Certificates of Analysis (COA) documenting purity, physical characteristics, and other critical parameters are provided as standard to guarantee supply reliability and product traceability.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
