ECHEMI Editorial Reference

Colorless or yellow liquid with a strong, fishy, amine-like odor.
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.
Cyclohexylamine appears as a clear colorless to yellow liquid with an odor of ammonia. Flash point 90°F. Irritates the eyes and respiratory system. Skin contact may cause burns. Less dense than water. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion.|Liquid; PelletsLargeCrystals, Liquid|Liquid|COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR.|Colorless to yellow liquid with an odor of ammonia.|Colorless or yellow liquid with a strong, fishy, amine-like odor.
