1-Methoxy-2-propanol

1-Methoxy-2-propanol (CAS 107-98-2), also known as PGME or Propylene Glycol Methyl Ether, is a slow-evaporating glycol ether solvent.

Where is 1-Methoxy-2-propanol used?

• Coatings: improves flow and leveling in waterborne and solvent-based architectural and industrial systems, reducing surface defects
• Adhesives and sealants: dissolves or dilutes resin components for consistent viscosity and open time
• Printing inks: supports pigment dispersion and controls drying speed
• Personal care formulators incorporate it as a solvent and carrier in hair sprays, skin toners, and nail treatments.
• Used in the chemical industry as a synthesis intermediate for the production of propylene glycol monomethyl ether acetate.
• Added as a penetrating oil additive in metal cleaning products.

Good to know: Buyers should confirm purity specifications and isomer content, particularly the ratio relative to 2-methoxy-1-propanol, when sourcing for sensitive formulation work.
