Amino-PEG-Amine is a class of polyethylene glycol (PEG) derivatives that contain functional groups, such as primary amine (-NH2) and terminal amino (-NH) groups. These functional groups make Amino-PEG-Amine a versatile tool for pharmaceutical research and development. Amino-PEG-Amines are commonly used as building blocks in drug delivery systems, where they can be conjugated to therapeutic agents or used as excipients to improve drug solubility, stability, and bioavailability. Additionally, Amino-PEG-Amines have been employed in the development of diagnostic imaging agents, where they can be labeled with radionuclides or fluorescent dyes to target specific biological molecules or tissues. Due to their unique properties, Amino-PEG-Amines have become an essential component in the development of novel drug formulations and imaging agents for clinical applications.
