Methyl formate CAS#107-31-3
Methyl Formate, also known as methyl methanoate, is the methyl ester of formic acid. The simplest example of an ester, it is a clear liquid with an ethereal odour, high vapor pressure, and low surface tension. It is an aromatic compound found in apples (Neubeller and Buchloh, 1986), and was identified as a volatile constituent in brewed, roasted, and dried coffee (Lovell et al., 1980); Methyl formate is used primarily to manufacture formamide, dimethylformamide, and formic acid. It is also used as a solvent for quick-drying finishes such as lacquers and in organic synthesis.

Product Application of Methyl formate CAS#107-31-3
Methyl formate is used primarily to manufacture formamide, dimethyl formamide, and formic acid. Because of its high vapor pressure, it is used for quick - drying finishes. It is also used as an insecticide and to manufacture certain pharmaceuticals. Foam Supplies, Inc. has trademarked Ecomate, which is used as a blowing agent for foam insulation, as a replacement for CFC, HCFC, or HFCs, with zero ozone depletion potential and < 25 global warming potential.
