Polyethylenglykol

Beschreibung:
Polyethylenglykol (PEG), mit der CAS-Nummer 25322-68-3, ist ein vielseitiges Polymer, das für seine hydrophilen Eigenschaften und Biokompatibilität bekannt ist. Es besteht aus sich wiederholenden Einheiten von Ethylenoxid, was zu einer Struktur führt, die im Molekulargewicht variieren kann, was seine physikalischen und chemischen Eigenschaften beeinflusst. PEG ist typischerweise eine farblose, geruchlose und viskose Flüssigkeit oder ein wachsartiger Feststoff, abhängig von seinem Molekulargewicht. Es ist in Wasser und vielen organischen Lösungsmitteln löslich, was es in einer Vielzahl von Anwendungen nützlich macht, einschließlich Pharmazie, Kosmetik und Lebensmittelprodukten. PEG dient als Schmiermittel, Feuchthaltemittel und Emulgator und wird häufig in Arzneimittelformulierungen verwendet, um die Löslichkeit und Bioverfügbarkeit zu verbessern. Darüber hinaus macht seine ungiftige Natur und die Fähigkeit, Hydrogels zu bilden, es wertvoll in biomedizinischen Anwendungen, wie z.B. Arzneimittelabgabesystemen und Gewebeengineering. Die spezifischen Eigenschaften von PEG können jedoch erheblich variieren, abhängig von seinem Molekulargewicht und seiner Formulierung, was bei der Auswahl für bestimmte Anwendungen berücksichtigt werden muss.

  • 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

    Kontrolliertes Produkt
    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>
