Polyethylene glycol

Description:
Polyethylene glycol (PEG), with the CAS number 25322-68-3, is a versatile polymer known for its hydrophilic properties and biocompatibility. It is composed of repeating units of ethylene oxide, resulting in a structure that can vary in molecular weight, which influences its physical and chemical characteristics. PEG is typically a colorless, odorless, and viscous liquid or a waxy solid, depending on its molecular weight. It is soluble in water and many organic solvents, making it useful in a wide range of applications, including pharmaceuticals, cosmetics, and food products. PEG serves as a lubricant, humectant, and emulsifier, and is often used in drug formulations to enhance solubility and bioavailability. Additionally, its non-toxic nature and ability to form hydrogels make it valuable in biomedical applications, such as drug delivery systems and tissue engineering. However, the specific properties of PEG can vary significantly with its molecular weight and formulation, which must be considered when selecting it for particular applications.

    Applications Poly(ethylene Glycol) molecules of an average molecular mass of 30,000. Poly(ethylene Glycol) is used in various applications from industrial chemistry to biological chemistry. Recent research has shown PEG maintains the ability to aid the spinal cord injury recovery process, helping the nerve impulse conduction process in animals. In rats, it has been shown to aid in the repair of severed sciatic axons, helping with nerve damage recovery. It is industrially produced as a lubricating substance for various surfaces to reduce friction. PEG is also used in the preparation of vesicle transport systems in with application towards diagnostic procedures or drug delivery methods.

  • Bis-dPEG®5, Half Benzyl Half NHS Ester

    CAS:

    Bis-dPEG®5, Half Benzyl Half NHS Ester is a heterobifunctional cross-linking reagent, which is derived from discrete poly(ethylene glycol) chemistry. It features a benzyl group on one end and an N-hydroxysuccinimide (NHS) ester on the other. The NHS ester is a well-known active ester that facilitates the formation of stable amide bonds with primary amines, commonly found on proteins and peptides. By doing so, it enables the covalent attachment of biomolecules, enhancing solubility, stability, and overall bioavailability.

  • Poly(ethylene oxide) - average Mv 200,000

    Controlled Product
    CAS:
    Polyethylene oxide is a linear polymer with an average molecular weight of 200,000. It has a viscosity of approximately 8,000-10,000 cps and is soluble in water. Polyethylene oxide can be used as an excipient for pharmaceutical products. This material is not toxic or carcinogenic and does not cause hypersensitivity reactions. It is metabolized by the liver and excreted in the bile. The polyethylene oxide molecule contains hydrophilic ethylene oxide (EO) and hydrophobic oxyethylene (OE) groups that are responsible for its solubility in water and its low toxicity. The EO groups are responsible for the high viscosity of polyethylene oxide, while the OE groups contribute to its low toxicity.
