CAS 25322-68-3

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.

Poly(ethylene oxide) - average Mv 200,000

Prodotto controllato

CAS: 25322-68-3

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.

Bis-dPEG®5, Half Benzyl Half NHS Ester

CAS: 25322-68-3

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.
