2-Methoxypropane

Updated: 2026-09-11

Overview

2-Methoxypropane, commonly referred to as isopropyl methyl ether, is an organic compound belonging to the ether class. It is a colorless, volatile liquid with a characteristic ether-like odor. Due to its low boiling point and high volatility, it is primarily used as a solvent in various industrial applications. The compound is synthesized through the reaction of isopropanol with methanol under specific catalytic conditions. Its molecular structure, featuring an oxygen atom bonded to two alkyl groups, contributes to its solvent properties and reactivity in organic synthesis.

Physical and Chemical Properties

2-Methoxypropane exhibits typical ether properties, including low density and high volatility. With a boiling point of 34-36°C, it evaporates quickly at room temperature, making it suitable for applications requiring fast-drying solvents. Its slight solubility in water contrasts with its miscibility in most organic solvents, enhancing its versatility. The compound's flammability is a critical consideration, with a flash point below -20°C. It forms explosive vapor-air mixtures, necessitating careful handling and storage. Its reactivity with strong oxidizing agents and acids further underscores the need for proper safety protocols in industrial settings.

Main Applications

2-Methoxypropane serves as an effective solvent in organic synthesis, particularly for reactions requiring non-polar or weakly polar media. Its ability to dissolve a wide range of organic compounds makes it valuable in pharmaceutical and chemical manufacturing. Additionally, it is used in extraction processes to isolate specific compounds from mixtures. In some formulations, it acts as a fuel additive to improve combustion characteristics. Its low toxicity and volatility also make it a candidate for specialized cleaning applications in electronics and precision engineering.

Safety and Storage

Due to its high flammability, 2-Methoxypropane must be stored in tightly sealed containers away from heat, sparks, and open flames. Proper grounding of equipment is essential to prevent static discharge, which could ignite vapors. Storage areas should be well-ventilated and equipped with explosion-proof fixtures. Personal protective equipment (PPE), including gloves and safety goggles, is mandatory during handling. In case of spills, immediate containment with inert absorbents is recommended. Regulatory guidelines, such as those from OSHA and NFPA, provide detailed protocols for safe handling and emergency response.

B2B Procurement Guide

When procuring 2-Methoxypropane, buyers should specify purity grades (e.g., ≥99% for laboratory use) and packaging options (drums, IBCs, or bulk shipments). Supplier certifications, such as ISO 9001, ensure quality consistency. Logistics planning must account for its flammable nature, requiring compliant transportation and storage solutions. Long-term contracts with suppliers can stabilize pricing, especially given market fluctuations in raw materials like methanol. Buyers should also evaluate regional regulatory requirements, such as TSCA or REACH compliance, to avoid legal or operational disruptions.
