Polyethylene glycol 200 can be used as:

• A structure-directing agent to synthesize iron vanadate (FeVO₄) nanoparticles via co-precipitation method.
• An organic additive to prepare crystalline nanorods of calcium tungstate (CaWO₄) using calcium chloride and sodium tungstate via solvothermal process.
• A surface modifier in the synthesis of calcium peroxide nanoparticles using CaCl₂ as a precursor via hydrolysis-precipitation method.
• A green solvent in combination with H₂O in the preparation of 4-sulfanylcoumarins by sulfanylation of 4-tosyloxycoumarins with thiourea and alkyl halides.
