Descripción

Características y beneficios

Hydroxy-dPEG₂₄-t-butyl ester is a versatile building block based upon a monodispersed polyethylene glycol (PEG) chain, comparable to a polymeric PEG₁₀₀₀. The single molecular weight, discrete-length PEG (dPEG) chain is 86 atoms (88.5 Å) long. A primary alcohol group terminates one end of the molecule. The opposite end is a propionic acid group protected as the tert-butyl ester. The terminal hydroxy group can be functionalized with various reactive groups to permit direct modification of surfaces, small molecules, or biomolecules. The tert-butyl ester deprotects with trifluoroacetic acid (TFA), exposing the terminal propionic acid, which can then be activated as the NHS or TFP ester or directly coupled to an amine using a suitable carbodiimide.
