Polietilenoglicol

Descrição:
Polietilenoglicol (PEG), com o número CAS 25322-68-3, é um polímero versátil conhecido por suas propriedades hidrofílicas e biocompatibilidade. É composto por unidades repetitivas de óxido de etileno, resultando em uma estrutura que pode variar em peso molecular, o que influencia suas características físicas e químicas. O PEG é tipicamente um líquido incolor, inodoro e viscoso ou um sólido ceroso, dependendo de seu peso molecular. É solúvel em água e muitos solventes orgânicos, tornando-o útil em uma ampla gama de aplicações, incluindo produtos farmacêuticos, cosméticos e alimentares. O PEG serve como lubrificante, umectante e emulsificante, e é frequentemente utilizado em formulações de medicamentos para melhorar a solubilidade e a biodisponibilidade. Além disso, sua natureza não tóxica e capacidade de formar hidrogéis o tornam valioso em aplicações biomédicas, como sistemas de liberação de medicamentos e engenharia de tecidos. No entanto, as propriedades específicas do PEG podem variar significativamente com seu peso molecular e formulação, o que deve ser considerado ao selecioná-lo para aplicações particulares.

    Produto Controlado
    CAS:

    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

    Produto Controlado
    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.
