1-Decylamine is a intermediate forming the phosphatidylcholine-decylamine liposomal membranes.

Decylamine has been used as:
Amine in the synthesis of dynole-2-24 by reductive amination with 1-(3-(dimethylamino)propyl)-1H-indole-3-carbaldehyde.
A modifier in the synthesis of nanocomposites based on poly(butylene terephthalate) and C60 nanoparticles.
A template in the synthesis of ordered two and three dimensional mesoporous iron oxide.

Decylamine (C10H21NH2) is a primary alkylamine with a long hydrophobic tail. Decylamine molecules were directly intercalated as guest molecules into a layered silicate, octosilicate, with hydrogen ions in the interlayers (H-octosilicate) as a host material by using a wet process with various solvents of different polarities and decylamine solubilities. Using a solvent with a relatively high polarity promoted the intercalation of decylamine molecules. In particular, when water, a poor solvent for decylamine, was used, the decylamine molecules were well-ordered in the interlayer space of H-octosilicate. The interlayer distance corresponded to double the length of the decylamine molecule, suggesting the formation of a decylamine bilayer in the interlayer space. The study suggests that the solvation of decylamine molecules can determine the structure of intercalated octosilicate compounds. n-decylamine is a good inhibitor of zinc in hydrochloric acid solution. Halide ions enhanced the corrosion of zinc, whereas n-decylamine inhibited the corrosion of zinc. The inhibitor efficiency of n-decylamine is increased significantly by halide ions. A consistent surface coverage value is obtained from weight loss and polarization studies, and n-decylamine acts mainly as a cathodic inhibitor[1-2].
