t-Boc-Aminooxy-PEG-Oxyamine is a compound widely used in pharmaceutical research and development due to its unique functional groups. The molecule contains a tert-butyloxycarbonyl (t-Boc) protecting group, an aminooxy functional group, and a polyethylene glycol (PEG) spacer. The t-Boc group provides stability to the compound during synthesis and purification, while the aminooxy group is reactive towards carbonyl groups, enabling it to form stable oxime bonds with aldehydes and ketones. The PEG spacer imparts solubility to the compound and can also modulate its pharmacokinetic properties. These functional groups make t-Boc-Aminooxy-PEG-Oxyamine a valuable tool in drug discovery, particularly for the design and synthesis of prodrugs, conjugates, and drug delivery systems.
