Cyclohexylamine (CHA) (CAS 108-91-8) is a Technical Grade primary amine supplied as a clear, flammable liquid with a fishy odor and a minimum purity of 99%, used as a neutralizing amine in boiler water treatment and as an intermediate for rubber accelerators and herbicides. With a 99% min purity, it provides effective pH control and metal surface protection in steam-generating systems.
This flammable, colorless-to-yellow liquid possesses a distinct fishy odor and is completely miscible with water. In boiler water treatment, it acts as a neutralizing amine, preventing carbonic acid corrosion in condensate lines.
CHA is also a vital building block in the synthesis of artificial sweeteners, rubber accelerators, and herbicides. Its high reactivity makes it indispensable for the production of various agrochemicals and industrial surfactants.
