t-Boc-Aminooxy-PEG4-acid - 97%, high purity , CAS No.2062663-68-5
Basic Description Synonyms 3,6,9,12,15-Pentaoxa-2-azaoctadecanedioic acid, 1-(1,1-dimethylethyl) ester | CS-0114864 | F82576 | Boc-aminoxy-PEG4-acid | BP-24427 | t-Boc-Aminooxy-PEG4-acid | 2,2-Dimethyl-4-oxo-3,6,9,12,15,18-hexaoxa-5-azahenicosan-21-oic acid | DTXSID801143758 | 2062 Specifications & Purity ≥97% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description t-Boc-Aminooxy-PEG4-acid is a PEG derivative containing a Boc-protected aminooxy group and a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. The Boc-protected amine can be deprotected under mild acidic conditions.
