Product Technical Details

Product Overview

1-Methoxy-2-propanol (CAS 107-98-2), commonly known as propylene glycol methyl ether (PGME), is a high-performance glycol ether widely utilized in industrial formulations due to its excellent solvency, low toxicity profile, and favorable environmental characteristics. As a colorless, transparent liquid with high water solubility and moderate volatility, it serves as a critical building block in the synthesis of active agrochemical ingredients, including the herbicide Metolachlor (CAS 51218-45-2).

Industrial Applications

Primarily classified as a chemical intermediate, 1-Methoxy-2-propanol plays a pivotal role in the manufacture of crop protection agents. Beyond agrochemical synthesis, it functions as an active solvent, coupling agent, and dispersant across multiple sectors:

  • Formulation of water-based and solvent-based coatings, enhancing flow and leveling.
  • Solvent system component in printing inks, ballpoint pen fluids, and industrial cleaners.
  • Coupling agent in hard-surface cleaners, rust removers, and glass cleaner blends—often combined with propylene glycol n-butyl ether.
  • Carrier solvent for nitrocellulose and additive in brake fluid and detergent formulations.
  • Fuel antifreeze and extraction medium in specialty chemical processes.

Storage should occur in a cool, dry, well-ventilated area with containers tightly sealed, away from strong oxidizers, acid chlorides, and moisture due to its flammability and reactivity profile.
