Methoxypoly(ethylene glycol) is a PEG ether synthesized via the ethoxylation of methanol with ethylene oxide. It serves as a critical hydrophilic modifier in pharmaceutical formulations. The general molecular formula is CH3(OCH2CH2)nOH, with CAS numbers varying by chain length (e.g., 25921-76-0).
Strictly store in a cool, dry place below 25°C to prevent degradation. Avoid inhalation of dust; use appropriate PPE. Not suitable for direct injection without rigorous purification to remove residual monomers.
