Mal-PEG4-CH2COOH

CAS: 1286754-10-6

Mal-PEG4-CH2COOH is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Mal-PEG4-CH2COOH is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.

Formula: C₁₄H₂₁NO₈

Purity: Min. 95%
