Description

Didodecyldimethylammonium Nitrite is a quaternary ammonium salt with a nitrite counterion, valued for its dual functionality as a cationic surfactant and a corrosion inhibitor. This compound is particularly significant for its ability to form protective films on metal surfaces, offering long-term stability in challenging environments. It is primarily needed by industries involved in metalworking, oil and gas production, and as a component in specialized biocidal and antistatic formulations where surface activity and corrosion protection are critical.

Application

• Metalworking Fluids & Corrosion Inhibitors: A key active ingredient in formulations for cutting oils, coolants, and rust preventatives, providing excellent protection for ferrous and non-ferrous metals.
• Oilfield Chemicals: Used in drilling muds, completion fluids, and pipeline treatments to inhibit corrosion in downhole and transport infrastructure.
• Industrial Biocides & Disinfectants: Functions as a cationic surfactant with antimicrobial properties in disinfectant concentrates for hard surfaces and industrial water systems.
• Antistatic Agents: Incorporated into polymers, coatings, and fuels to dissipate static electricity and prevent spark hazards.
• Phase Transfer Catalyst: Facilitates reactions between reactants in immiscible phases in specialty organic synthesis.
• Clay Stabilizer: Used in enhanced oil recovery and geotechnical applications to control swelling in clay-rich formations.
• Textile & Leather Auxiliaries: Serves as a softener, antistatic agent, and processing aid in fiber and leather treatment baths.
• Research & Development: Employed in academic and industrial R&D for studying surfactant behavior, corrosion science, and novel material synthesis.

Quality Control

Our Didodecyldimethylammonium Nitrite is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) detailing key specifications such as assay, moisture content, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to minimize degradation and moisture uptake. Keep away from strong acids, strong bases, and incompatible materials.
