Dimethyldecylamine

Dimethyldecylamine (CAS 1120-24-7) is a tertiary aliphatic amine with the molecular formula C12H27N, commercially available under trade names including ADMA 10, Farmin DM 10P, and Decyldimethylamine. It carries no assigned E-code and is registered under EC number 214-302-7, compliant with REACH regulations across European markets.

In water treatment, dimethyldecylamine functions as a precursor to quaternary ammonium biocides, where its tertiary nitrogen undergoes quaternisation to deliver antimicrobial activity against bacteria and algae. In oilfield applications, it acts as a corrosion inhibitor by adsorbing onto metal surfaces through its nitrogen lone pair, forming a protective barrier against acidic media.

The product is supplied as a liquid in standard industrial packaging, including drums and IBCs, and meets REACH registration requirements for European supply chains. Procurement teams should confirm grade specifications and SDS documentation directly with the supplier to ensure compliance with application-specific regulatory frameworks.
