Phthalimidooxy-PEG4-NHS ester is a protected aminooxy compound with an NHS ester-linked to a Phthalimide moiety via four discrete PEG units. It enables the installation of a hydrophilic, protected aminooxy group on peptides, proteins, small molecules, and amine-functionalized surfaces. Upon deprotection, the aminooxy group forms stable oxime bonds with aldehydes and ketones. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
