trans-1,2-cyclohexanediaminetetraacetic acid monohydrate (CyDTA)(
1) is a chelating agent having high sequestration capacity. Chelating agents capture ionized metals in various industrial water and work to remove some chemical hindrances caused by metal ions.
1 forms coordinate bonds to multivalent metal ions at a 1:1 molar ratio in water. In addition,
1 shows higher chelating ability than ethylenediaminetetraacetic acid (EDTA). Therefore,
1 is an efficient chelating agent and has been widely used in industrial fields.
