Bromomethyl methyl ether is a reactive organic compound used primarily as a methoxymethylating agent in chemical synthesis, where it transfers the CH3OCH2– group to install the methoxymethyl (MOM) protecting group on alcohols, phenols and other nucleophiles. It is a colorless liquid with a pungent odor, handling requires care due to its toxicity and flammability. CAS: 13057-17-5, molecular formula: C2H5BrO, molecular weight: 124.96 g/mol. Store at 2 to 8 °C. Signal word: Warning. Molekula supplies Bromomethyl methyl ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
