1, 4, 7, 10-Tetraazacyclododecane (CAS 294-90-6)
The 1, 4, 7, 10-tetraazacyclododecane, also known as cyclen, is a nuclear magnetic resonance (NMR) contrast agent injected into human tissues or organs. The density of the chemical product is either higher or lower than surrounding tissues, the contrast caused by which is displayed in the form of magnetic resonance imaging (MRI).
The 1, 4, 7, 10-tetraazacyclododecane comes as white crystalline powder, providing high purity of 99%. The 1, 4, 7, 10-tetraazacyclododecane is used as medicine intermediate, and also contrast media for magnetic resonance imaging (MRI) in medical diagnosis. The composition made of cyclen together with heavy metal can serve as X ray contrast medium. Additionally, the cyclen have countless applications to chemical simulation, molecular recognition, molecular magnet, as well as biological and chemical catalysts.
