Tri Hexadecyl Amine, identified by its CAS number 28947-77-5, is a fascinating molecule with significant industrial relevance. As a tertiary amine, its structure comprises a central nitrogen atom bonded to three long C16 hexadecyl chains (C48H99N). This substantial hydrocarbon portion is key to its unique properties and wide-ranging applications, particularly as a chemical intermediate. Understanding the chemistry behind this compound is vital for researchers and procurement specialists aiming to leverage its full potential.

The physical form of Tri Hexadecyl Amine is typically a white to light yellow solid at standard room temperature (25°C). Its molecular weight is approximately 688.33 g/mol. The presence of three long fatty alkyl chains imparts significant lipophilicity (oil-loving) to the molecule, while the nitrogen atom provides a site for potential reactions. Its high purity, often specified at a minimum of 95%, is a critical factor for its performance in downstream applications. This purity ensures that unwanted side reactions are minimized and that the intended properties of derived products are achieved consistently.

The primary industrial significance of Tri Hexadecyl Amine lies in its role as a precursor for synthesizing quaternary ammonium salts. Through a process known as quaternization, the tertiary amine reacts with an alkylating agent (such as methyl chloride or benzyl chloride) to form a quaternary ammonium cation. These compounds are exceptionally versatile. For example, when quaternized with methyl groups, they form effective cationic surfactants used in fabric softeners, hair conditioners, and antistatic agents. The long hexadecyl chains contribute to excellent surface activity, making these derivatives potent emulsifiers and wetting agents.

Furthermore, the derivatives of Tri Hexadecyl Amine find application as disinfectants and antimicrobial agents due to their ability to disrupt cell membranes. This makes them invaluable in hygiene products, industrial cleaning solutions, and even in certain agricultural applications for crop protection. The ability to buy Tri Hexadecyl Amine and then process it into these high-value quaternary ammonium compounds makes it an economically attractive intermediate for chemical manufacturers.

For manufacturers seeking to purchase Tri Hexadecyl Amine, understanding its specifications, such as total amine value (79-83 mg KOH/g) and moisture content (0.5% max), is important for quality assurance. Sourcing from reputable chemical suppliers who can provide consistent quality and reliable technical support is crucial. Whether for large-scale industrial synthesis or specialized research and development, the demand for high-purity Tri Hexadecyl Amine continues to grow, underscoring its enduring importance in the chemical industry.
