(4-methoxyphenyl)-diphenyl-methylamino-PEG7 linker contains a TBDMS alcohol protecting group and a terminal hydroxyl group. TBDMS can be removed in the presence of acetyl chloride. The hydroxyl group can be derivatized to other reactive functional group for conjugation. The hydrophilic PEG linker can increase the solubility of compounds in aqueous media.
