C9H21N

C9H21N is the molecular formula for several isomers of nonylamine. Nonylamines are primary amines with the general formula C9H19NH2. The specific arrangement of the nine carbon atoms and one nitrogen atom determines the exact isomer. Common examples include n-nonylamine, which has a linear nine-carbon chain attached to the amino group, and various branched isomers like 2-nonylamine or 3-nonylamine. The physical and chemical properties of these isomers can vary depending on their structure.

Nonylamines are generally colorless to pale yellow liquids with a characteristic amine odor. They are typically soluble in organic solvents and have limited solubility in water. As primary amines, they exhibit basic properties and can react with acids to form salts. They can also undergo reactions typical of primary amines, such as alkylation, acylation, and condensation reactions.

The synthesis of nonylamines can be achieved through various methods, including the reduction of nonanenitrile or the amination of nonyl halides. The specific synthesis route often depends on the desired isomer and the availability of starting materials.

Nonylamines and their derivatives find applications in a range of industries. They can be used as intermediates in the synthesis of surfactants, corrosion inhibitors, and pharmaceuticals. Their properties also make them suitable for use as emulsifiers or as components in agricultural chemicals. The specific uses are often dictated by the unique structural features of each isomer.
