Reported in EPA TSCA Inventory.

Moderately toxic by ingestion. Inhalation of vapor can cause irritation to nasal passages and conjunctiva, optic neuritis, narcosis, retching, and death from pulmonary irritation. Industrial fatalities have occurred only with exposure to high concentrations. Flammable liquid. Very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. Explosive in the form of vapor when exposed to heat or flame. Reacts with methanol + sodium methoxide to form an explosive product. To fight fire, use alcohol foam, CO₂, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

 Methyl formate (CAS NO.107-31-3) is the methyl ester of formic acid. The simplest example of an ester, it is a clear liquid with an ethereal odor, high vapor pressure and low surface tension.In the laboratory, it can be produced by the condensation reaction of methanol and formic acid, as follows:
HCOOH + CH₃OH → HCOOCH₃ + H₂O
 Industrial  Methyl formate , however, is usually produced by the combination of methanol and carbon monoxide (carbonylation) in the presence of a strong base, such as sodium methoxide:
CH₃OH + CO → HCOOCH₃ 
 It is used primarily to manufacture formamide, dimethylformamide, 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. Under the trademark Ecomate, it is now used a a blowing agent for foam insulation, as a replacement for CFC, HCFC, or HFCs, with zero ozone depletion potential and zero global warming potential.
