It is a clear, colorless, flammable, liquid with a ammonia odor. Slightly soluble in water, easily soluble in ethanol, ether, acetone, benzene and chloroform.
1-Decylamine is a intermediate forming the phosphatidylcholine-decylamine liposomal membranes.
Decylamine was used in the synthesis of dynole 2-24 series by undergoing reductive amination with 1-(3-(dimethylamino)propyl)-1H-indole-3-carbaldehyde. It was also used as a coordinating solvent to thermolyse the lead piperidine and lead tetrahydroquinoline dithiocarbamate (DTC) complexes.
ChEBI: Decylamine is an alkylamine.
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 is a hydrophobic long alkylated cationic ammonium that is used to modify the polarity of reversed phases on octadecylsilyl (ODS) gels.
Poison by ingestion and
skin contact. A skin irritant. Flammable
when exposed to heat or flame; can react
with oxidizing materials. To fight fue, use
alcohol foam, foam, dry chemical. When
heated to decomposition it emits toxic
fumes of NOx. See AMINES and AMINES,

Properties and Applications
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].
