Polietilenglicol

Descripción:
Polietilenglicol (PEG), con el número CAS 25322-68-3, es un polímero versátil conocido por sus propiedades hidrofílicas y biocompatibilidad. Está compuesto por unidades repetitivas de óxido de etileno, lo que resulta en una estructura que puede variar en peso molecular, lo que influye en sus características físicas y químicas. El PEG es típicamente un líquido incoloro, inodoro y viscoso o un sólido ceroso, dependiendo de su peso molecular. Es soluble en agua y muchos disolventes orgánicos, lo que lo hace útil en una amplia gama de aplicaciones, incluyendo productos farmacéuticos, cosméticos y alimentarios. El PEG sirve como lubricante, humectante y emulsionante, y a menudo se utiliza en formulaciones de medicamentos para mejorar la solubilidad y la biodisponibilidad. Además, su naturaleza no tóxica y su capacidad para formar hidrogeles lo hacen valioso en aplicaciones biomédicas, como sistemas de liberación de fármacos e ingeniería de tejidos. Sin embargo, las propiedades específicas del PEG pueden variar significativamente con su peso molecular y formulación, lo que debe tenerse en cuenta al seleccionarlo para aplicaciones particulares.

  • Bis-dPEG&reg;5, Half Benzyl Half NHS Ester

    CAS:
    <p>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.</p>

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

    Producto controlado
    CAS:
    <p>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.</p>
