DOTA and NOTA are important intermediates for the synthesis of diagnostic reagents and therapeutic drugs. 
Radioactive metal elements need to be labeled through bifunctional chelating agents such as DOTA and NOTA molecules, which is currently a commonly used labeling method for PD-1/PD-L1 targeted radionuclide
probes. Especially in the manufacture of contrast agents for medical imaging techniques such as magnetic resonance imaging (MRI), X-ray CT, and ultrasound imaging, as well as in the development of 
radioactive therapeutic drugs for malignant tumors, DOTA, NOTA and their derivatives have shown extremely important application value.
