Di-methyl PEG

Di-methyl PEG consists of polyethylene glycol chains with methyl groups capping both terminals, providing a non-reactive and hydrophobic end structure. The symmetrical methyl termination in Di-methyl PEG enhances molecular stability and prevents undesired chemical reactions at the chain ends. Di-methyl PEG is commonly used as an inert spacer, phase-transfer catalyst, or non-ionic surfactant in formulations and material science.
