mPEG-OH

mPEGₙ-OH is a fundamental class of monofunctional polyethylene glycol derivatives serving as versatile precursors for synthesizing advanced PEG-based conjugates (e.g., linkers, surfactants) and modifying biomaterials, with representative compounds like mPEG₂₄-OH offering tunable hydrophilicity and biocompatibility through defined PEG chain lengths. While their terminal hydroxyl group enables flexible chemical functionalization, these molecules typically serve as intermediates rather than final-functionalized components in bioconjugation and formulation workflows.
