HOOC-PEG9-COOH is a PEG product that is known as acid PEG or homobifunctional PEG. It is a highly versatile compound that finds application in various industries, including pharmaceuticals, cosmetics, and biotechnology. HOOC-PEG9-COOH is widely used for its ability to modify the properties of biomolecules and enhance their solubility, stability, and bioavailability. With a molecular weight of 500 Da, HOOC-PEG9-COOH consists of a polyethylene glycol (PEG) backbone with nine ethylene glycol units. The carboxylic acid groups at both ends of the molecule provide functionalization sites for conjugation with other molecules or surfaces. One of the key advantages of HOOC-PEG9-COOH is its water solubility, which allows for easy formulation in aqueous systems. This makes it an ideal choice for drug delivery systems, where it can improve the pharmacokinetic properties of

Bis-PEG9-acid, a cleavable PEG-based linker, is utilized for PROTACs and ADCs synthesis.

Bis-dPEG®21-Acid is a PEG polymer categorised as homobifunctional PEG (X-PEG X). Used as a linker, bis-dPEG®21-Acid is used to attached PEG to proteins, peptides, oligonucleotides, nanoparticles and small molecules via pegylation, a bioconjugation technique.

m-dPEG®12-TFP Ester 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. m-dPEG®12-TFP Ester 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.

Bis-PEG25-acid

Bis-dPEG®25-Acid is a PEG polymer categorised as homobifunctional PEG (X-PEG X). Used as a linker, bis-dPEG®25-Acid is used to attached PEG to proteins, peptides, oligonucleotides, nanoparticles and small molecules via pegylation, a bioconjugation technique.

Bis-dPEG®13-Acid is a PEG polymer categorised as homobifunctional PEG (X-PEG X). Used as a linker, bis-dPEG®13-Acid is used to attached PEG to proteins, peptides, oligonucleotides, nanoparticles and small molecules via pegylation, a bioconjugation technique.

Amino-dPEG®4-t-Butyl Ester 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. Amino-dPEG®4-t-Butyl Ester 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.
