Boc-NH-PEG12-NH2(CAT: I016269) is a heterobifunctional polyethylene glycol (PEG) linker consisting of a 12-unit PEG chain terminated with a Boc-protected amine at one end and a free primary amine at the other. The PEG12 spacer imparts flexibility, hydrophilicity, and enhanced solubility, while also reducing steric hindrance during conjugation. The Boc-protected amine serves as a latent functional handle that can be selectively deprotected under acidic conditions, allowing controlled sequential modifications. The free amine readily reacts with activated esters, carboxylic acids, or other electrophiles to form stable amide linkages. This reagent is useful for bioconjugation, drug delivery, polymer functionalization, and advanced material design.
