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.
