Propylene glycol methyl ether (PM), CAS 107-98-2, also known as propylene glycol monomethyl ether or 1-methoxy-2-propanol, is a colorless transparent liquid with a slight ether odor and no strong irritant odor. Its molecular formula is C4H10O2 and its molecular weight is 90.12. Propylene glycol methyl ether exhibits good solubility, appropriate volatilization rate, and reactive activity, making it a slightly toxic and environmentally friendly solvent. In industries such as coatings, inks, printing and dyeing, acrylates, copper clad laminates, etc., it is commonly used as a solvent, dispersant, and diluent. It can also be used as a fuel antifreeze, extractant, and raw material for organic synthesis. Additionally, propylene glycol methyl ether is widely applied in water-based coatings, solvent-based printing inks, ballpoint and fountain pen inks, household and industrial cleaners, agricultural pesticides, and other fields.
