Hydroxy-dPEG®24-t-butyl ester, product number QBD-10722, is a versatile building block based upon a monodispersed polyethylene glycol (PEG) chain. 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. Alternatively, the hydroxy group can react with isothiocyanates or active esters of carboxylic acids to form new conjugates. The tert-butyl ester deprotects with trifluoroacetic acid (TFA) or formic acid, 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.
