In the complex world of industrial chemistry, certain molecules serve as foundational building blocks, enabling the creation of a vast array of specialized products. N,N-Dimethyloctadecylamine, bearing the CAS number 124-28-7, is one such critical intermediate. As a leading manufacturer and supplier, we recognize its significance, particularly in the production of cationic surfactants and other high-value chemicals. This article aims to shed light on the properties that make N,N-Dimethyloctadecylamine so industrially important and where you can reliably source it.

Key Chemical Properties of N,N-Dimethyloctadecylamine

N,N-Dimethyloctadecylamine is characterized by its molecular formula C20H43N, indicating a molecule with a substantial carbon chain. Its structure comprises a tertiary amine group attached to an eighteen-carbon saturated alkyl chain (octadecyl group). This unique structure imparts specific physical and chemical properties:

  • Tertiary Amine Functionality: The nitrogen atom, bonded to three carbon atoms (two methyl groups and one octadecyl group), possesses a lone pair of electrons. This makes it nucleophilic and reactive, enabling it to undergo quaternization reactions.
  • Long Alkyl Chain: The C18 chain provides significant hydrophobicity (lipophilicity) to the molecule. This long, non-polar chain is crucial for its downstream applications, especially in creating surfactants that interact with oil and grease, and materials with conditioning properties.
  • Physical State: Typically appearing as a clear, colorless to yellow liquid at room temperature, its melting point is around 23°C, suggesting it can solidify in cooler conditions. Its boiling point is quite high, approximately 347°C, indicating low volatility.
  • Solubility: While the long alkyl chain makes it poorly soluble in water, it is generally soluble in organic solvents, which is advantageous for many chemical synthesis processes.

These properties collectively position N,N-Dimethyloctadecylamine as an ideal precursor for molecules that require both a reactive head group and a substantial hydrophobic tail.

Industrial Significance and Applications

The primary industrial value of N,N-Dimethyloctadecylamine stems from its role as an intermediate in synthesizing quaternary ammonium salts. These derivatives are widely utilized as:

  • Cationic Surfactants: Essential for fabric softeners, hair conditioners, and antistatic agents due to their affinity for negatively charged surfaces like textile fibers and hair. The long C18 chain contributes significantly to the softening and conditioning effects.
  • Disinfectants and Biocides: Certain quaternary ammonium compounds derived from this amine exhibit strong antimicrobial properties, effectively disrupting microbial cell membranes.
  • Specialty Chemicals: It can also be a precursor for other specialty chemicals, including certain types of insect repellents, by undergoing specific reactions.

The consistent demand for these end-products fuels the need for a reliable supply of high-quality N,N-Dimethyloctadecylamine.
