Polietilenglicole

Descrizione:
Polietilenglicole (PEG), con il numero CAS 25322-68-3, è un polimero versatile noto per le sue proprietà idrofili e biocompatibilità. È composto da unità ripetitive di ossido di etilene, risultando in una struttura che può variare in peso molecolare, il che influisce sulle sue caratteristiche fisiche e chimiche. Il PEG è tipicamente un liquido incolore, inodore e viscoso o un solido ceroso, a seconda del suo peso molecolare. È solubile in acqua e in molti solventi organici, rendendolo utile in un'ampia gamma di applicazioni, tra cui prodotti farmaceutici, cosmetici e alimentari. Il PEG funge da lubrificante, umettante ed emulsionante, ed è spesso utilizzato nelle formulazioni farmaceutiche per migliorare la solubilità e la biodisponibilità. Inoltre, la sua natura non tossica e la capacità di formare idrogeli lo rendono prezioso in applicazioni biomediche, come sistemi di somministrazione di farmaci e ingegneria dei tessuti. Tuttavia, le proprietà specifiche del PEG possono variare significativamente con il suo peso molecolare e formulazione, il che deve essere considerato quando si sceglie per applicazioni particolari.

    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

    Prodotto controllato
    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.
