• Convenient organic-soluble source of formaldehyde; alternative to Paraformaldehyde, A11313, or formalin in many reactions. e.g. chloromethylation of aromatics; e.g. polystyrene: J. Am. Chem. Soc., 112, 8187 (1990). For reviews of chloromethylation, see: Org. React., 1, 63 (1942); Russ. Chem. Rev., 46, 891 (1977). Caution! carcinogenic bis(chloromethyl) ether is formed in these reactions.
