Dimethoxymethane
Description
Dimethoxymethane (CAS 109-87-5), commercially known as Methylal, is a fast-evaporating solvent used across pharmaceutical manufacturing, specialty chemical synthesis, and flavoring applications.
Its low boiling point and clean evaporation profile make it a preferred choice where residue-free solvent performance is a procurement priority for industrial manufacturers and labs.
In pharmaceutical manufacturing, Methylal functions as a reaction solvent and extraction medium where controlled evaporation and low residual contamination are critical to API quality.
Flavor formulators incorporate it as a carrier solvent and flavoring agent, particularly in applications requiring rapid volatilization of aromatic compounds in various mixtures.
In specialty chemical synthesis, it acts as a formaldehyde equivalent and catalyst precursor for producing polyoxymethylene dimethyl ethers and other acetal-based intermediates.
Industrial cleaning and aerosol formulations also use it as a co-solvent to improve solvency and reduce VOC content in finished products across many different sectors.
Dimethoxymethane is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for larger industrial volumes and high-capacity manufacturing needs.
Food-grade and pharmaceutical-grade specifications are available to meet FCC and USP compliance requirements. Technical-grade material is standard for industrial solvent use.
