Tos-PEG2-OH is a bench-stable, moisture-tolerant PEG-based linker featuring a tosyl (Tos) group at one end and a terminal hydroxyl for conjugation. This dual-functional architecture enables efficient coupling in bioconjugation workflows, particularly where orthogonal reactivity or controlled release is required. The short PEG spacer provides enhanced solubility without compromising stability.
Tos-PEG2-OH serves as a versatile bifunctional building block for the synthesis of PEGylated compounds, enabling efficient conjugation via its tosylate group while retaining a reactive hydroxyl terminus. Its bench-stable nature and excellent solubility in common organic solvents facilitate straightforward purification and compatibility with diverse reaction conditions. Widely employed in peptide modification and drug delivery systems, it supports precise control over molecular weight and functionalization in biopharmaceutical applications.
