The chemical compound represented by the formula HCOOCH2H2O is a molecular structure that combines formic acid (HCOOH), methanol (CH3OH), and water (H2O). This compound is also known as methyl formate, which is an ester formed from formic acid and methanol. Let’s break down the components and structure of this compound, as well as its various uses in different industries.
Chemical Structure and Composition
The compound HCOOCH2H2O can be described as consisting of three primary components:
- Formic acid (HCOOH): The simplest carboxylic acid, composed of a single carbon atom, a carboxyl group (-COOH), and a hydrogen atom.
- Methanol (CH3OH): A simple alcohol containing one carbon atom, three hydrogen atoms, and one hydroxyl group (-OH).
- Water (H2O): A well-known chemical compound composed of two hydrogen atoms bonded to one oxygen atom.
When these components combine, they form methyl formate (HCOOCH2), which is the ester derived from the reaction between methanol and formic acid. The water molecule (H2O) is often associated with the esterification process or as a byproduct in the formation of the ester. In many cases, water is involved in the production of methyl formate, particularly in aqueous solutions or reactions where water is a medium.
Methyl Formate (HCOOCH2) Properties
- Molecular Formula: HCOOCH2
- Molar Mass: 60.05 g/mol
- Appearance: Methyl formate is a colorless liquid with a faint, fruity odor.
- Boiling Point: Approximately 32.7°C (90.9°F)

Applications of Methyl Formate
Methyl formate has a range of practical applications, particularly in industrial processes. Here are some key uses of this compound:
- Solvent in Organic Synthesis: Methyl formate is widely used as a solvent in the chemical industry, especially in reactions involving organic compounds. Its low boiling point and ability to dissolve a variety of substances make it useful for specific chemical syntheses.
- Intermediate in Chemical Manufacturing: Methyl formate is often used as an intermediate in the production of formic acid derivatives and various other chemicals. It is involved in several reactions in which the formate group (HCOO-) plays a key role in synthesizing more complex molecules.
- Fumigant and Insecticide: Methyl formate has been used as a fumigant in pest control, particularly for controlling pests in stored grains. Its ability to penetrate effectively into materials makes it useful in the disinfection of food storage facilities.
- Plasticizers and Lubricants: Due to its properties as a solvent, methyl formate is also used in producing plasticizers and lubricants, helping to modify the physical properties of various polymers and compounds.
- Flavors and Fragrances: The fruity smell of methyl formate makes it an ingredient in the production of synthetic flavors and fragrances. Its aroma resembles that of apples and is used in flavoring food products.
Safety Considerations
Methyl formate is generally regarded as a moderately hazardous chemical, with potential health effects upon exposure. It is important to handle it with care and adhere to safety protocols, especially when working with concentrated forms of the compound. Prolonged or high-level exposure can lead to irritation of the eyes, skin, and respiratory system. As with many chemicals, proper ventilation, protective equipment, and storage conditions are necessary to minimize risks.
Conclusion
HCOOCH2H2O, or methyl formate, is an ester formed from the reaction of methanol and formic acid, often appearing in various industrial and laboratory processes. Its versatility as a solvent, intermediate in chemical synthesis, fumigant, and component in flavor and fragrance production makes it an important compound in various fields. However, like all chemicals, it must be handled with care to avoid any potential health hazards.
