Description

N,n-Dimethylicosylamine is a tertiary amine surfactant and chemical intermediate of significant industrial importance. Its unique structure, featuring a long alkyl chain, provides excellent surface-active properties and reactivity, making it a versatile building block for formulators. This compound is primarily utilized in the production of quaternary ammonium compounds (quats), corrosion inhibitors, and specialty surfactants across diverse sectors. Industries such as oilfield chemicals, agrochemicals, and personal care rely on its consistent quality and performance.

Application

• Quaternary Ammonium Salt (Quat) Synthesis: A key precursor for manufacturing fabric softeners, biocides, and disinfectants.
• Oilfield & Corrosion Chemistry: Used in formulating corrosion inhibitors, demulsifiers, and drilling fluid additives for upstream and midstream operations.
• Agrochemical Intermediates: Serves as a building block for certain herbicides, pesticides, and adjuvants that enhance product efficacy.
• Specialty Surfactants: Employed in the synthesis of amphoteric and cationic surfactants for personal care and industrial cleaning products.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases in fine chemical and pharmaceutical synthesis.
• Polymer & Resin Modifiers: Acts as an intermediate or additive to modify the properties of polymers and epoxy curing agents.

Quality Control

Our N,n-Dimethylicosylamine is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay by GC or titration, identity confirmation (IR), and control of key impurities. A Certificate of Analysis (COA) detailing all test results 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, well-ventilated area away from strong oxidizing agents and acids. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and oxidation.
