Uses
|
Cyclen is a very important intermediate for the synthesis of diagnostic reagents and therapeutic drugs. It has a wide range of applications, such as: removing stones in the human body, inhibiting the damage caused by myocardial ischemic reperfusion. Especially in the manufacture of contrast agents for medical imaging technologies like nuclear magnetic resonance imaging (MRI), X-ray CT, and ultrasound imaging, as well as radiotherapeutic drugs for malignant tumors , cyclen and its derivatives have shown extremely important application value.
