Description

3-Octadecylaminopropiononitrile CAS NO 6281-72-7 is a high-purity, long-chain alkylaminonitrile derivative, valued for its role as a versatile intermediate in organic synthesis. Its molecular structure, featuring both a primary amine and a nitrile group, makes it a critical building block for creating surfactants, corrosion inhibitors, and specialized polymers. This compound is essential for R&D and production teams in the fine chemical, agrochemical, and material science industries seeking to develop novel functional additives and surface-active agents.

Application

• Surfactant & Emulsifier Intermediate: A key precursor for synthesizing cationic and amphoteric surfactants used in personal care, textile processing, and industrial cleaning formulations.
• Corrosion Inhibitor Synthesis: Serves as a building block for creating long-chain amine-based corrosion inhibitors, particularly for protecting metals in acidic environments and oilfield applications.
• Polymer Modification: Used to introduce hydrophobic alkyl chains and functional amine/nitrile groups into polymers, enhancing properties like adhesion, water resistance, and compatibility.
• Agrochemical Intermediates: Employed in the synthesis of certain herbicides, fungicides, and plant growth regulators that require a lipophilic amine component.
• Lubricant & Fuel Additive Precursor: A starting material for manufacturing additives that improve lubricity, detergency, and anti-wear properties in oils and fuels.
• Pharmaceutical Research Intermediate: Utilized in medicinal chemistry for the development of novel drug candidates, particularly those targeting lipid membranes or requiring long alkyl chains for bioavailability.
• Organocatalyst & Ligand Synthesis: The amine functionality allows for its use in constructing ligands for metal complexes or as a component of organocatalysts.

Quality Control

Our 3-Octadecylaminopropiononitrile is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (IR, NMR), to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, moisture content, and related substances. Our quality system is designed to meet the stringent requirements of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from strong oxidizing agents.
