General description

Buffered picric acid-paraformaldehyde fixative is suitable for use in electron microscopy and light-microscopic immunocytochemistry.

Application

Paraformaldehyde was used in the preparation of azomethine ylide, required for the synthesis of amine-modifying single-walled carbon nanotubes. It was also used in the preparation of α-methylenechromanes, α-methylenequinoline and ortho-quinone methides.
