O-(2-carboxyethyl)polyethylene glycol 3400

Description:

O-(2-Carboxyethyl)polyethylene glycol 3400, commonly referred to as PEG 3400, is a water-soluble polymer characterized by its polyethylene glycol backbone modified with a carboxyethyl group. This modification enhances its hydrophilicity and biocompatibility, making it suitable for various biomedical applications, including drug delivery and tissue engineering. The molecular weight of approximately 3400 g/mol indicates that it consists of a moderate number of repeating ethylene glycol units, contributing to its viscosity and solubility in aqueous solutions. The presence of the carboxyethyl group introduces functional sites that can participate in further chemical reactions, allowing for conjugation with other molecules or drugs. This property is particularly valuable in the development of targeted therapies and controlled release systems. Additionally, PEG 3400 exhibits low toxicity and immunogenicity, which are critical factors for its use in pharmaceutical formulations. Overall, its unique combination of hydrophilicity, functionalization potential, and biocompatibility makes O-(2-carboxyethyl)polyethylene glycol 3400 a versatile compound in the field of medicinal chemistry and materials science.

m-dPEG®37-acid

CAS: 117786-94-4

m-dPEG®37-acid 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®37-acid 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.
