m-dPEG®25-acid, product number 10328, is a long (77 atoms, 89.9 Å), methyl-capped, discrete chain length polyethylene glycol (dPEG®) spacer. The reactive end of the molecule terminates in a propionic acid group. This product is the precursor to PN11290, m-dPEG®25-TFP ester, and PN11291, m-dPEG®25-NHS ester. Also, m-dPEG®25-acid is part of a broad line of amine-reactive m-dPEG® spacers. The dPEG® spacer lengths range from 2 to 49 ethylene glycol units and terminate in propionic acid or an active ester.
