Methyl formate
Methyl formate (CAS: 107-31-3, HCO2CH3) is a volatile, flammable ester with a molar mass of 60.05 g/mol. It is a clear, colourless liquid that serves as a fundamental building block in organic synthesis. Its applications span various chemical processes, notably as a source of the formyl group and in the production of formic acid and formamide. It is also used as a solvent and as a refrigerant.

Chemical Synthesis
Methyl formate is widely employed as a key intermediate and building block in organic synthesis. It is a primary reagent for introducing the formyl group into organic molecules, enabling the construction of more complex compounds.
Solvent Applications
Due to its solvent properties, methyl formate is utilised in various industrial applications. It can be found in formulations for specialised cleaning agents and as a solvent in certain chemical reactions where its volatility and solvency are advantageous.
Refrigerant
Historically and in specific niche applications, methyl formate has been used as a refrigerant. Its thermodynamic properties allow it to function as a working fluid in refrigeration cycles, though its flammability requires careful handling.
Precursor for Other Chemicals
It serves as a precursor for the synthesis of other essential chemicals, including formic acid and formamide. These downstream products have broad industrial relevance in textiles, agriculture, and pharmaceuticals.
