CAS 9004-74-4

Polyethylene glycol monomethyl ether

Description:

Polyethylene glycol monomethyl ether (PEG-ME), with the CAS number 9004-74-4, is a non-ionic surfactant and polymer that is widely used in various applications, including pharmaceuticals, cosmetics, and industrial processes. It is characterized by its hydrophilic nature due to the presence of polyethylene glycol (PEG) chains, which enhances its solubility in water and compatibility with other substances. PEG-ME typically exhibits low toxicity and is considered safe for use in many formulations. Its molecular structure includes a methyl ether group, which contributes to its unique properties, such as improved stability and reduced viscosity compared to other PEG derivatives. The substance is often utilized as a solvent, emulsifier, or thickening agent, and it can also enhance the bioavailability of drugs in pharmaceutical applications. Additionally, PEG-ME is known for its ability to form films and improve the texture of products, making it valuable in cosmetic formulations. Overall, its versatility and favorable characteristics make PEG-ME a widely used compound in various industries.

Poly-(ethylenglykol)-methylether-Mn 550

CAS: 9004-74-4

Poly(ethylenglycol) methyl ether Mn 550 is a polymer that has been synthesized by the reaction of MnCl2 and ethylene glycol. The thermal expansion coefficient for this polymer is about 1.8x10^-5/K, which can be used to determine the temperature changes in the environment. The ionization mass spectrometry analysis shows that it consists of Mn and oxygen atoms. This polymer has a diameter of around 2 nm, which can be determined by transmission electron microscopy (TEM). Poly(ethylenglycol) methyl ether Mn 550 has been shown to have catalase activity, which is an enzyme that breaks down hydrogen peroxide into water and oxygen gas. It also has growth kinetics that are dependent on the concentration of the polymer.
