Applicazioni

It finds its application as a convenient organic-soluble source of formaldehyde; alternative to paraformaldehyde or formalin in many reactions. e.g. chloromethylation of aromatics; e.g. polystyrene. It is also used in homolytic formylation of heterocycles, used for organic synthesis, and in fuel.

Note

Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
