DTPA-tetra (t-Bu ester) (CAS: 174267-71-1) is a protected derivative of diethylenetriamine pentaacetic acid (DTPA), featuring four tert-butyl ester groups. This compound is commonly used as a precursor for creating DTPA-based chelators. The tert-butyl esters protect the carboxyl groups during synthesis, allowing for targeted modifications before deprotection. Once deprotected, it forms a strong chelator capable of binding metal ions, making it suitable for radiolabeling and metal ion coordination in diagnostic and therapeutic applications.
Key Features:
- Type: Protected DTPA derivative with tert-butyl esters
- Function: Precursor for DTPA-based chelators; protects carboxyl groups during synthesis
- Applications:
- Radiolabeling
- Diagnostic imaging
- Metal ion coordination
- Therapeutic applications
- Advantages: Easy modification, strong metal chelation after deprotection
