Description

mPEG-Butyraldehyde, also known as mPEG-bALD, is a linear monofunctional PEG derivative with a methoxy (CH3-O-) group at obe end of the PEG chain and a butyraldehyde (bALD) functional group at the other. This compound is used in bioconjugation and surface modification applications due to the reactivity of its butyraldehyde group.  

Key Features and Applications:

  • Reactive Butyraldehyde Group: The butyraldehyde group readily reacts with amino groups (amines) or hydrazide groups on biomolecules or surfaces, enabling the introduction of specific functionalities.    
  • Bioconjugation: mPEG-Butyraldehyde is used in bioconjugation reactions, where it is used to modify proteins, peptides, antibodies, and other biomolecules. This modification can enhance stability, solubility, and biological activity.  \
  • Surface Modification: This compound can modify the surface properties of materials, such as nanoparticles, microparticles, and biosensors. By introducing PEG chains and functional groups, surface modification can improve biocompatibility, reduce non-specific binding, and improve the performance of various devices.   
  • Drug Delivery: mPEG-Butyraldehyde can be used to create drug delivery systems, where it can be used to conjugate drugs to carriers or to modify the surface of drug delivery vehicles. This modification can improve drug stability, target specificity, and controlled release.    
  • Imaging and Diagnostics: mPEG-Butyraldehyde can be used in imaging and diagnostic techniques, like fluorescence labeling and magnetic resonance imaging (MRI). By conjugating imaging agents to mPEG-Butyraldehyde, enhanced contrast and sensitivity. 
  • Cell Culture: mPEG-Butyraldehyde can be used to modify cell culture surfaces, improving cell adhesion and proliferation.

Solubility

  • Aqueous Solutions: soluble in water, but its solubility can decrease as the molecular weight of the PEG chain increases.
  • Organic Solvents: is generally soluble in most organic solvents, including alcohols, ethers, and chlorinated hydrocarbons.
