POLYETHYLENE GLYCOL 400
Polyethylene glycol 400 (PEG 400) is a low-molecular-weight grade of polyethylene glycol with a low-level toxicity. It is very hydrophilic, which renders it a useful ingredient in drug formulations to augment the solubility and bioavailability of weakly water-soluble drugs.
This medication is used to relieve dry, irritated eyes. Common causes for dry eyes include wind, sun, heating/air conditioning, computer use/reading, and certain medications.
Polyethylene glycol (PEG-400) was found to be an inexpensive, non-toxic, and effective medium for the one-pot synthesis of 1,2-disubstituted benzimidazoles in excellent yields. Eco-friendliness, low cost, high yields, and recyclability of the PEG-400 are the important features of this protocol.
