Dodecane Tetraacetic Acid (DOTA) is a synthetic, chelating agent widely used in medical and biochemical applications. Structurally, it belongs to the family of macrocyclic polyamines and has high affinity for binding metal ions, particularly lanthanides and radioactive isotopes. DOTA is pivotal in diagnostic imaging and targeted radiotherapy due to its ability to form stable complexes with metallic elements.

Key Features:

1. Chemical Structure: A macrocyclic compound with four acetic acid groups attached to a dodecane framework, enhancing its metal-binding capacity.
2. Applications:
   • Used as a ligand for radiopharmaceuticals in imaging techniques like PET and SPECT.
   • Facilitates delivery of therapeutic radionuclides in cancer treatment.
3. Stability: Forms highly stable complexes, minimizing toxicity and improving efficacy in medical applications.
