Hydroxy-PEG3-SS-PEG3-alcohol CAS:5662-81-7 is a compound used in pharmaceuticals that contains functional groups such as hydroxyl (-OH), thiol (-SH), and ether (-O-) linkages. The compound is commonly used as a linker molecule to connect drugs or other molecules of interest to larger carrier molecules, such as antibodies, in a process known as PEGylation.
The hydroxyl group (-OH) on the molecule can participate in hydrogen bonding and can improve the solubility of hydrophobic drugs. The thiol group (-SH) can form disulfide bonds with other thiol groups, making it useful for introducing stability in drugs or targeting delivery to specific tissues. The ether linkage (-O-) provides flexibility to the molecule, enabling it to assume different conformations for effective binding and interaction with target receptors or enzymes.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
