Fmoc-N-PEG7-acid（Cat No.:I015982）is a polyethylene glycol derivative featuring a seven-unit PEG chain terminated with a carboxylic acid and an Fmoc-protected amine group. The PEG7 backbone imparts excellent hydrophilicity, flexibility, and reduced steric hindrance, making it ideal for conjugation and linker design. The Fmoc group provides base-labile protection, allowing selective deprotection during solid-phase synthesis. This reagent is widely applied in peptide chemistry, drug discovery, and bioconjugation, where it serves as a versatile tool for protein modification, polymer functionalization, and the creation of advanced biomaterials and therapeutic conjugates.
