Introduction

Cyclohexylamine is an organic compound, belonging to the aliphatic amine class. It is a colorless liquid, although like many amines, samples are often colored due to contaminants. It has a fishy odor and is miscible with water. Like other amines, it is a weak base, compared to strong bases such as NaOH, but it is a stronger base than its aromatic analog, aniline.
