Jeong, Hyeri published the artcileEfficient Synthesis and Characterization of Monoprotected Symmetrical Poly(Ethylene Glycol) Diamine, HPLC of Formula: 42074-68-0, the publication is Bulletin of the Korean Chemical Society (2018), 39(1), 29-32, database is CAplus.
Solid-phase synthesis of monoprotected poly(ethylene glycol) (PEG) diamine is demonstrated. 2-Chlorotrityl chloride (2-CTC) resin was used as a solid support for inducing monofunctionalization using excess PEG diamine. Fmoc-monoprotected PEG was prepared from 2-CTC resin and fully characterized by high-performance liquid chromatog. and electrospray ionization mass spectrometry. We envision that this strategy will provide an efficient method of preparing various kinds of heterobifunctional PEG mols. without a need for further purification steps.
