I. [Product Description]
DTPA-PEG-COOH (Diethylenetriaminepentaacetic acid-Polyethylene glycol-Carboxyl) is a multifunctional organic intermediate with both chelating coordination and hydrophilic modification properties. The DTPA group in its molecule can efficiently chelate metal ions, and the carboxyl terminal is easy for derivatization modification. This compound can be used as a pharmaceutical intermediate for the construction of bio-conjugation systems or as a carrier in catalytic reactions to improve the reaction efficiency.
