Formamidine acetate is used as an intermediate in the synthesis of active pharmaceutical ingredients. It is also used as a condensing agent for the preparation of pyrimidine and imidazole heterocycles.

Bemerkungen

Hygroscopic. Moisture sensitive. Incompatible with oxidizing agents.

Literaturverweise

More convenient source of formamidine than the corresponding chloride in that it is non-hygroscopic and, being the salt of a weaker acid, can often be used in synthesis without the need to liberate the free base.

Widely used in heterocyclic syntheses, for example of pyrimidine and imidazole derivatives.
