CAS 542-88-1 — Bis-(Chloromethyl)ether

Bis-(Chloromethyl)ether (BCME) is a highly reactive organochlorine compound primarily used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty polymers. It is also employed in research for derivatizing alcohols and phenols. This colorless liquid has a strong, ether-like odor and requires careful handling due to its toxicity and instability. Bis-(Chloromethyl)ether has a CAS number of 542-88-1, with the molecular formula C₂H₄Cl₂O and a molecular weight of 114.9586 g/mol. It must be stored at -18°C or below to maintain stability, though it carries no EU classification signal word. Molekula supplies Bis-(Chloromethyl)ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
