Methyl Formate CAS 107-31-3
Methyl formate is a formic acid ester that appears as a colorless, transparent, and volatile liquid at room temperature with a pleasant odor. It is soluble in water, alcohols, and ethers, and can be saponified by water and alkaline solutions. The compound is easily hydrolyzed in the presence of moisture. Its vapor can form explosive mixtures with air, with an explosive concentration range of 6.0%–20.0% (v/v). As an important intermediate in organic synthesis, methyl formate is widely used in the production of fragrances, solvents, organic synthesis chemicals, bactericides, and insecticides.
