【Structural Formula】
1. Product Property
Dipropylene glycol methyl ether (DPM) is a clear, colorless liquid with a mild ether-like odor. It exhibits excellent solvency properties, being miscible with water and most organic solvents. The compound has a low volatility (vapor pressure: 0.3 mmHg at 20°C) and high boiling point (190°C). Its balanced hydrophilic/lipophilic character makes it an effective coupling agent. DPM shows good chemical stability and is biodegradable under aerobic conditions.

3. Application Scope and Usage
DPM is widely used as a solvent in coatings, inks, and cleaning formulations due to its balanced evaporation rate and solvency power. It serves as an active component in paint strippers and degreasers. The chemical is employed in electronic cleaning fluids and precision cleaning applications. In personal care products, it functions as a carrier solvent for fragrances. DPM is also utilized in agricultural formulations and as an intermediate for chemical synthesis. Its low toxicity profile makes it suitable for consumer product applications when used within recommended guidelines.
4. Package and Storage
DPM is typically packaged in 200L steel drums, 1000L IBC containers, or bulk tankers. Storage should be in cool, well-ventilated areas away from heat sources and oxidizing agents. Containers must be kept tightly closed to prevent moisture absorption. The product is stable under normal conditions with a recommended shelf life of 24 months. During handling, use chemical-resistant gloves and eye protection.
