ButyrAldehyde-PEG-Valeric Acid (bALD-PEG-VA), MW 2K is a versatile, bifunctional linker molecule, combining a reactive butyraldehyde group with a carboxylic acid moiety through a 2000 Da polyethylene glycol (PEG) spacer. This unique structure enables efficient conjugation of biomolecules, enhancing solubility, stability, and pharmacokinetics. Widely employed in pharmaceutical research and development, it facilitates targeted drug delivery, prodrug synthesis, and bioconjugate formation, thus accelerating the discovery and optimization of novel therapeutics, while minimizing off-target effects and improving biocompatibility.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
